func IntParam ¶

func IntParam(i int64) NullInt

func (*NullInt) UnmarshalText ¶

func (f *NullInt) UnmarshalText(text []byte) error

type PocketSphinx ¶

type PocketSphinx struct {
	Config Config
	// contains filtered or unexported fields
}

PocketSphinx is a speech recognition decoder object

func NewPocketSphinx ¶

func NewPocketSphinx(config Config) *PocketSphinx

NewPocketSphinx creates PocketSphinx instance with Config.

func (*PocketSphinx) EndUtt ¶

func (p *PocketSphinx) EndUtt() error

EndUtt ends utterance processing.

func (*PocketSphinx) Free ¶

func (p *PocketSphinx) Free()

Free releases all resources associated with the PocketSphinx.

func (*PocketSphinx) GetHyp ¶

func (p *PocketSphinx) GetHyp(segment bool) (Result, error)

GetHyp gets speech recognition result for best hypothesis. If segment is true, result contains word segments in recognized text.

func (*PocketSphinx) GetInSpeech ¶

func (p *PocketSphinx) GetInSpeech() bool

func (*PocketSphinx) GetNbest ¶

func (p *PocketSphinx) GetNbest(numNbest int, segment bool) []Result

func (*PocketSphinx) ProcessRaw ¶

func (p *PocketSphinx) ProcessRaw(raw []byte, noSearch, fullUtt bool) error

ProcessRaw processes a single channel, 16-bit pcm signal. if noSearch is true, ProcessRaw performs only feature extraction but don't do any recognition yet. if fullUtt is true, this block of data is a full utterance worth of data.

func (*PocketSphinx) ProcessUtt ¶

func (p *PocketSphinx) ProcessUtt(raw []byte, numNbest int, segment bool) ([]Result, error)

func (*PocketSphinx) StartStream ¶

func (p *PocketSphinx) StartStream() error

StartUtt starts utterance processing.

func (*PocketSphinx) StartUtt ¶

func (p *PocketSphinx) StartUtt() error

StartUtt starts utterance processing.

type Result ¶

type Result struct {
	Text     string    `json:"text"`
	Score    int64     `json:"score"`
	Prob     int64     `json:"prob"`
	Segments []Segment `json:"segments"`
}

Result is a speech recognition result

type Segment ¶

type Segment struct {
	Word       string `json:"word"`
	StartFrame int64  `json:"start_frame"`
	EndFrame   int64  `json:"end_frame"`
	Prob       int64  `json:"log_posterior_probability. "`
	AcScore    int64  `json:"acoustic_score"`
	LmScore    int64  `json:"languagemodel_score"`
	Lmbackoff  int64  `json:"languagemodel_backoff"`
}

Segment represents a word segment contains frame infomations and probabirity

func GetSegments ¶

func GetSegments(ps *C.ps_decoder_t) []Segment

GetSegments returns word segment list for best hypotesis

func GetSegmentsForNbest ¶

func GetSegmentsForNbest(nb *C.ps_nbest_t) []Segment

GetSegments returns word segment list for nbest_t
