[Open the source ](https://azure.microsoft.com/en-us/products/ai-foundry/tools/speech) ## A speech service for applications Azure Speech in Foundry Tools provides speech recognition, voice generation, audio translation and other speech features. Users may previously have encountered these tools through Speech Studio. Choose the current service and documentation rather than creating a separate account for each familiar name. Integrate through SDKs, REST APIs and other developer tools. The invocation method depends on the task: live speech, a short file and a large recording collection need different workflows. Some scenarios offer containers or deployment near the data, but this does not make every feature work offline without an account or contractual terms. ## Testing recognition on your material Use a short practice recording without personal information and prepare a manual transcript first. Include a name, a number and a specialist term. Compare these after recognition, along with quiet word endings and a noisy passage. Fluent text alone does not show whether important terms or amounts were captured accurately. If you need synthesis, turn the same task into a spoken instruction and check the voice separately. Pronunciation settings and SSML control delivery where supported, but listening is still necessary. A voice application also needs interruption handling, clear failure messages and a distinction between a spoken reply and a confirmed action. ## A transcript remains a draft Notes and published quotations need different levels of checking. For notes, you can mark an uncertain passage and continue; for a quotation, compare the words with the recording. Keep text linked to its source, and correct names, numbers and terms before treating a transcript as reliable evidence. ## Access terms and usage planning Official documentation covers languages, regions and billing options. Charges may depend on recognized audio duration, synthesis text volume and additional features. Do not apply one operation’s allowance to the whole service. Before production use, estimate typical volume, repeated requests and source recording storage. Containers have their own requirements and are not equivalent to a free ready application. Particular features, including personal voice creation, may require additional permissions. For enterprise data, review resource access and material transfer and storage rules. Your own control recordings help assess changes after switching language, model or configuration. ## Suitable tasks - Integrate speech recognition into an application - Create narration through a speech API - Verify translation and voice scripts Features ## Strengths - Microsoft speech models, SDKs and REST APIs - Documented languages and deployment options Things to consider ## Limitations - Terms vary by feature and region - Containers do not make every mode work offline ## Selection and conditions Free access Not confirmed Trial period Not confirmed No sign-up required Not confirmed Russian interface Not confirmed Local installation Yes API Yes “Not confirmed” means there is not enough information. The feature may still be available; check the developer’s terms. Input formats Audio, Text Result Text, Audio ### Terms An Azure resource and suitable access are required. Languages, regions, billing and special permissions vary by feature; containers do not make every mode work offline. From task to first result ## Practical example Task Integrate speech recognition into an application What to prepare A short recording of your own conversation, with participants’ consent to processing. ### Task brief or prompt Task brief: transcribe the recording in its original language. Preserve the meaning of what is said; mark unclear passages separately and check them against the audio. Verify names, numbers and titles manually. ### Expected result A draft transcript; speech recognition does not guarantee that every utterance is correct. ### How to check the result - Listen to passages containing numbers and names. - Mark omissions and unclear passages; do not fill them in by guessing. An editorial teaching example of a task brief, not the result of hands-on testing of the service. Check that the required mode is available, that you have rights to the source material and that the intended use of the result is permitted.
