Basic Speech to Text Transcription

Convert speech to text with high accuracy. Supports multiple Indian languages and accents. Features include:

Multi-language support
Automatic language detection
High-quality noise filtering
Support for various audio formats

The input_audio_codec is an optional parameter. Our API automatically detects all codec formats, so you don’t necessarily need to pass this parameter. However, for PCM files specifically (pcm_s16le, pcm_l16, pcm_raw), you must pass this parameter. Note that PCM files are supported only at 16kHz sample rate.
