func ReqToSpeechRequest

func ReqToSpeechRequest(req interface{}) SpeechRequest

Converts a vtt.*Request to a SpeechRequest, which allows functions like DetectEndOfSpeech to work

func (*SpeechRequest) DetectEndOfSpeech

func (req *SpeechRequest) DetectEndOfSpeech() bool

Uses VAD to detect when the user stops speaking

func (*SpeechRequest) GetNextStreamChunk

func (req *SpeechRequest) GetNextStreamChunk() ([]byte, error)

Returns the next chunk in the stream as 16000 Hz PCM

func (*SpeechRequest) GetNextStreamChunkOpus

func (req *SpeechRequest) GetNextStreamChunkOpus() ([]byte, error)

Returns next chunk in the stream as whatever the original format is (OPUS 99% of the time)

func (*SpeechRequest) OpusDecode

func (req *SpeechRequest) OpusDecode(chunk []byte) []byte

func (*SpeechRequest) OpusDetect

func (req *SpeechRequest) OpusDetect() bool
