The example response is a JSON object that shows the names of audio-independent parameters that can be specified when initiating a transcription session and their default values.


Indicates the voice activity level below which the ASR engine considers any audio event to be silence.


Indicates the current buffer size configuration, which is the maximum amount of audio (seconds) to analyze for diarization.


Indicates the byte ordering of audio samples. In a BIG endian data word, the most significant byte comes first, when reading from left to right. In a LITTLE endian data word, the least significant byte comes first. By convention, LITTLE endian (the default) is the most common.


Indicates the amount of time an API request will wait for a response before timing out.


Indicates the languages that are available. The languages indicated are components of the model used by the ASR engine for transcription. These components convert the stream of sound symbols from an acoustic model into text.


Indicates the default language model, along with the models available for transcription requests.

The remaining JSON keys and values are audio-independent parameters and their default values. Most of these parameters never require modification, but are provided to enable tuning for special circumstances, such as aggressive real-time applications.

Both audio-independent and audio-dependent parameters are discussed in V‑Blaze Transcription Parameters.
