December 2025
Speech to Text (STT)
Added input_audio_codec: Introduced the input_audio_codec parameter, letting you explicitly declare the audio codec when automatic detection isn’t sufficient (for example, raw PCM streams).
Translate & Transliterate
Deprecated enable_preprocessing: Deprecated the enable_preprocessing parameter on the Translate and Transliterate APIs. Preprocessing behavior is now handled internally, so the parameter no longer needs to be set.
SDKs
TypeScript SDK: Released an updated TypeScript SDK version with improved generator settings and type coverage.
