Synchronous audio recognition

Synchronous audio recognition ensures fast response times and better works with small pre-recorded single-channel audio files.

If you want to recognize speech within a single connection, use streaming mode. In streaming mode, you can get intermediate recognition results.

Audio requirementsAudio requirements

The audio you provide must meet the following requirements:

• Maximum file size: 1 MB
• Maximum length: 30 seconds
• Maximum number of audio channels: 1

If your file is larger, longer, or has more audio channels, use asynchronous recognition.

SpeechKit can recognize audio in the following formats:

• LPCM
• OggOpus

For more information about format-specific features, see Supported audio formats.
