 We learn how to use the fast transcription API (via [Transcriptions - Transcribe](https://go.microsoft.com/fwlink/?linkid=2296107)) with the following scenarios:
 - [Known locale specified](?tabs=locale-specified): Transcribe an audio file with a specified locale. If you know the locale of the audio file, you can specify it to improve transcription accuracy and minimize the latency.
 - [Language identification on](?tabs=language-identification-on): Transcribe an audio file with language identification on. If you're not sure about the locale of the audio file, you can turn on language identification to let the Speech service identify the locale.

 |----------|-------------|----------------------|
 | `channels` | The list of zero-based indices of the channels to be transcribed separately. Up to two channels are supported unless diarization is enabled. By default, the fast transcription API merges all input channels into a single channel and then performs the transcription. If this isn't desirable, channels can be transcribed independently without merging.<br/><br/>If you want to transcribe the channels from a stereo audio file separately, you need to specify `[0,1]`, `[0]`, or `[1]`. Otherwise, stereo audio is merged to mono and only a single channel is transcribed.<br/><br/>If the audio is stereo and diarization is enabled, then you can't set the `channels` property to `[0,1]`. The Speech service doesn't support diarization of multiple channels.<br/><br/>For mono audio, the `channels` property is ignored, and the audio is always transcribed as a single channel.| Optional |
 | `diarization` | The diarization configuration. Diarization is the process of recognizing and separating multiple speakers in one audio channel. For example, specify `"diarization": {"maxSpeakers": 2, "enabled": true}`. Then the transcription file contains `speaker` entries (such as `"speaker": 0` or `"speaker": 1`) for each transcribed phrase. | Optional |
-| `locales` | The list of locales that should match the expected locale of the audio data to transcribe.<br/><br/>If you know the locale of the audio file, you can specify it to improve transcription accuracy and minimize the latency. If a single locale is specified, that locale is used for transcription.<br/><br/>But if you're not sure about the locale, you can specify multiple locales. Language identification might be more accurate with a more precise list of candidate locales.<br/><br/>If you don't specify any locale, or if the locales that you specify aren't in the audio file, then the Speech service still tries to identify the language. If the language can't be identified, an error is returned.<br/><br/>The supported locales that you can specify are: de-DE, en-IN, en-US, es-ES, es-MX, fr-FR, hi-IN, it-IT, ja-JP, ko-KR, pt-BR, and zh-CN.
