Feature Speech-to-Text has launched a new model, named chirp_telephony to bring the accuracy gains of our chirp model to telephony-specific use cases. The new model is a fine-tuned version of our very successful chirp model, based on the Universal large Speech Model(USM) architecture, on audio that originated from a phone call typically recorded at an 8 kHz sampling rate. For more information, see Speech-to-Text supported languages .
