Voximplant speech recognition for most of the languages is powered by Google Speech API. At the end of February Google introduced new Speech API capabilities including Enhanced speech recognition model for better quality of recognition (for video and phone calls). According to Google, this model offers the 62-64% Word Error Rate (WER) improvement compared to the standard one.

Voximplant developers can use this model by setting model to phone_call_enhanced in ASRParameters:

const asr = VoxEngine.createASR({
	profile: ASRProfileList.Google.en_US,
	model: ASRModelList.Google.phone_call_enhanced,
	singleUtterance: true
})

Please note that billing for enhanced recognition differs from the standard one as it requires more resources.
