Section 1 Description of Services

Bing Speech Recognition Control captures end user speech and converts the input to text (the "Service"). Microsoft provides access to the Service through an application programming interface (the "API").  You may use the API to design, develop and test your programs (the "Application") for use with other Microsoft products and services.  The API is available for download at the Bing Developer Center (the "Bing Developer Center"). The Bing Developer Center is located at and contains developer tools, materials, content and updates. The Bing Developer Center is governed by the Terms of Use available at (the "Bing Developer Center TOU"). 

Section 2 Acceptance of Terms

This Terms of Use is a contract between you and the Microsoft Company listed in Section 23. This contract applies to your use of the Service, the APIs, and any documentation, media, services, updates and other materials made available from time to time through the Bing Speech Recognition Control webpage of the Bing Developer Center. You can view the most current version of this contract at such webpage. Microsoft may update this contract by posting new terms and conditions. If you do not agree to the changes, you must stop using the API; if you do not, your use of the API continues under the changed contract. Your use of certain elements of the API may be subject to guidelines for additional Microsoft products and services, posted notices, or codes of conduct. These are incorporated by reference into this contract. 

By creating an account or accepting this contract, you represent that you are at least 18 years old or have reached the age of "majority" where you live, if that is not 18 years of age. If you are under 18 or have not reached the age of majority, your parent or legal guardian must set up an account on your behalf and accept this contract. Please note that Microsoft does not provide warranties for the Service. This contract also limits our liability. These terms are in sections 11 and 14. Please read them carefully. 

Your developer account may be used for up to 500,000 transactions of any type within any 30 day period across all your developer accounts, and Microsoft will enforce this transaction limit.  You may only use developer accounts for developing, testing and maintenance of the API with the Applications consistent with the terms of this Agreement.

Section 3 License

Subject to your compliance with this contract, Microsoft provides you a non-exclusive, nontransferable, nonsublicensable, worldwide license to:

  • use the API to create an unlimited number of Applications for the Windows client operating system so that the Application can interface directly with the Service;

  • use the API and access the Service to host and present results from the Service on the Application; and

  • use the documentation, media, and other materials made available by Microsoft from time to time for use with the Service and API solely in support of you exercising your rights in this license. 

Microsoft will provide you with the means for obtaining unique access credentials to access the Service through the API solely for the purposes stated in this license. You are solely responsible for: (a) keeping your access credentials confidential; and (b) any and all activities that occur under your access credentials. You must promptly notify Microsoft of any unauthorized use of your access credentials or any other breach of security. Microsoft will not be liable for any loss that you incur if someone else uses your access credentials, either with or without your knowledge. However, you could be held liable for losses incurred by Microsoft or another party if someone else uses your access credentials. 

The licenses granted above extend only to the software or derivative works that you create that run directly on a Microsoft Windows operating system product or Microsoft application platform (such as Microsoft Office or Microsoft Dynamics).

Section 4 Microsoft Marks

We may include our trademark(s) or logo(s) as part of the API.   If we do so, you will not remove, modify, or interfere with the display or viewing of these trademarks or logos.  In any display of trademarks, logos, or attribution, you will comply with the current version of our usage guidelines, which may be updated from time to time.  

Section 5 Reserve Right to Modify

Microsoft may change the Service or delete features of the Service at any time and for any reason. Microsoft may cancel or suspend your use of the Service at any time without notice and for any reason. Upon Service cancellation, your right to use the Service stops right away. 

Section 6 Use Restrictions

When using the Service you must comply with the terms of this contract, the terms of the Bing Developer Center TOU, all applicable laws, and the Microsoft Anti-Spam Policy ( You must also obey any policies, codes of conduct, and notices Microsoft provides. The Service may not be available in all countries. You, and any third party working on your behalf, may not:

  • Distribute, sell, resell, loan, rent, lease, sublicense, redistribute, assign or otherwise dispose your access credentials, or any part thereof, to any third party including to any affiliate;

  • Syndicate, distribute, publish, facilitate, enable, or allow access or linking to the Service directly from the API or any location or source other than the Application (or in any manner except directly to users through the Application);

  • Remove, modify, or tamper with any notice or link that is incorporated into the Service. 

If Microsoft believes that you are making unauthorized or improper use of the Service, Microsoft may take such action as it deems appropriate without notice to you. These actions may include blocking access to the Service and APIs from a particular access credential, internet domain, or IP address.  We may use technology or other means to protect the API, protect our customers, or stop you from breaching this contract.  These means may hinder or break your use of the API, and you may not work around or attempt to thwart or disable any of these technical or other means.  We also may, in our sole discretion, limit the rate at which the API may be called.  We may perform such throttling globally across all Microsoft services, per end user, or on any other basis.  You will not take steps to circumvent any technical measures we may put in place to enforce throttling. 

Microsoft may at all times: (a) disclose any information as Microsoft deems necessary to satisfy any applicable law, regulation, legal process or governmental request; or (b) edit or to remove any information or materials, in whole or in part.

Section 24 Binding Arbitration and Class Action Waiver If You Live in the United States.

This section applies to any dispute EXCEPT IT DOESN'T INCLUDE A DISPUTE RELATING TO THE ENFORCEMENT OR VALIDITY OF YOUR, MICROSOFT'S, OR EITHER OF OUR LICENSORS' INTELLECTUAL PROPERTY RIGHTS.  The term "dispute" means any dispute, action, or other controversy between you and Microsoft concerning the services (including their price) or this agreement, whether in contract, warranty, tort, statute, regulation, ordinance, or any other legal or equitable basis.  "Dispute" will be given the broadest possible meaning allowable under law.

(a)     Notice of Dispute. In the event of a dispute, you or Microsoft must give the other a Notice of Dispute, which is a written statement that sets forth the name, address, and contact information of the party giving it, the facts giving rise to the dispute, and the relief requested.  You must send any Notice of Dispute by U.S. Mail to Microsoft Corporation, ATTN: LCA ARBITRATION, One Microsoft Way, Redmond, WA 98052-6399, US.  A form is available on the Legal and Corporate Affairs (LCA) website ( Microsoft will send any Notice of Dispute to you by U.S. Mail to your address if we have it, or otherwise to your email address. You and Microsoft will attempt to resolve any dispute through informal negotiation within sixty (60) days from the date the Notice of Dispute is sent. After sixty (60) days, you or Microsoft may commence arbitration.

(b)     Small claims court. You may also litigate any dispute in small claims court in your county of residence or King County, Washington, if the dispute meets all requirements to be heard in the small claims court. You may litigate in small claims court whether or not you negotiated informally first.

(c)     Binding arbitration. If you and Microsoft don't resolve any dispute by informal negotiation or in small claims court, any other effort to resolve the dispute will be conducted exclusively by binding arbitration as described in this section. You are giving up the right to litigate (or participate in as a party or class member) all disputes in court before a judge or jury. Instead, all disputes will be resolved before a neutral arbitrator, whose decision will be final except for a limited right of appeal under the Federal Arbitration Act. Any court with jurisdiction over the parties may enforce the arbitrator's award.

(d)     Class action waiver. Any proceedings to resolve or litigate any dispute in any forum will be conducted solely on an individual basis. Neither you nor Microsoft will seek to have any dispute heard as a class action or in any other proceeding in which either party acts or proposes to act in a representative capacity. No arbitration or proceeding which either party acts or proposes to act in a representative capacity. No arbitration or proceeding will be combined with another without the prior written consent of all parties to all affected arbitrations or proceedings.

(e)    Arbitration procedure. Any arbitration will be conducted by the American Arbitration Association (the "AAA") under its Commercial Arbitration Rules. If you are an individual and use the services for personal or household use, or if the value of the dispute is $75,000 or less whether or not you are an individual or how you use the services, its Supplementary Procedures for Consumer-Related Disputes will also apply. For more information, see the American Arbitration Association website ( or call 1-800-778-7879. To commence arbitration, submit the form available on the Legal and Corporate Affairs (LCA) website ( to the AAA. You agree to commence arbitration only in your county of residence or in King County, Washington, US. Microsoft agrees to commence arbitration only in your county of residence. You may request a telephonic or in-person hearing by following the AAA rules. In a dispute involving $10,000 or less, any hearing will be telephonic unless the arbitrator finds good cause to hold an in-person hearing instead. The arbitrator may award the same damages to you individually as a court could. The arbitrator may award declaratory or injunctive relief only to you individually, and only to the extent required to satisfy your individual claim.

(f)    Arbitration fees and incentives.

      i. Disputes involving $75,000 or less. Microsoft will promptly reimburse your filing fees and pay the AAA's and arbitrator's fees and expenses. If you reject Microsoft's last written settlement offer made before the arbitrator was appointed ("Microsoft's last written offer"), your dispute goes all the way to an arbitrator's decision (called an "award"), and the arbitrator awards you more than Microsoft's last written offer, Microsoft will give you three incentives: (i) pay the greater of the award or $1,000; (ii) pay twice your reasonable attorney's fees, if any; and (iii) reimburse any expenses (including expert witness fees and costs) that your attorney reasonably accrues for investigating, preparing, and pursuing your claim in arbitration. The arbitrator will determine the amount of fees, costs, and expenses unless you and Microsoft agree on them.

      ii. Disputes involving more than $75,000. The AAA rules will govern payment of filing fees and the AAA's and arbitrator's fees and expenses.

      iii. Disputes involving any amount. In any arbitration you commence, Microsoft will seek its AAA or arbitrator's fees and expenses, or your filing fees it reimbursed, only if the arbitrator finds the arbitration frivolous or brought for an improper purpose. In any arbitration Microsoft commences, Microsoft will pay all filing, AAA, and arbitrator's fees and expenses. Microsoft won't seek its attorney's fees or expenses from you in any arbitration. Fees and expenses are not counted in determining how much a dispute involves.

      iv. Conflict with AAA rules. This agreement governs to the extent it conflicts with the AAA's Commercial Arbitration Rules and Supplementary Procedures for Consumer-Related Disputes.

      v. Claims or disputes must be filed within one year. To the extent permitted by law, any claim or dispute under this agreement must be filed within one year in small claims court (Section 24(b)), an arbitration proceeding (Section 24(c)), or in court, if Section 24(f)(vi) permits the dispute to be filed in court instead of arbitration. The one-year period begins when the claim or Notice of Dispute first could be filed. If a claim or dispute isn't filed within one year, it's permanently barred.

      vi. Severability. If the class action waiver in Section 24(d) is found to be illegal or unenforceable as to all or some parts of a dispute, then Section 24 won't apply to those parts. Instead, those parts will be severed and proceed in a court of law, with the remaining parts proceeding in arbitration. If any other provision of this Section 24 is found to be illegal or unenforceable, that provision will be severed with the remainder of Section 24 remaining in full force and effect.
