Detailed Description

Class for online Opus audio stream processing (voice activity detection and speech statistics computation)

Member Function Documentation

addPacket()

virtual void voicesdk::SpeechSummaryStreamOpus::addPacket ( const uint8_t *  bytes, size_t  bytesNum  )

pure virtual

Adds Opus packet to process.

Parameters

bytes	A buffer containing single Opus packet. It is expected that packet contains data for single mono stream
bytesNum	Number of bytes

Exceptions

std::runtime_error

if runtime error occurred

create()

static SpeechSummaryStreamOpus::Ptr voicesdk::SpeechSummaryStreamOpus::create ( const std::string &  initPath, size_t  sampleRate  )

static

Creates SpeechSummaryStreamOpus instance.

Parameters

initPath	Initialization data path
sampleRate	Audio sampling rate in Hz

Returns

Smart pointer to created SpeechSummaryStreamOpus instance

Exceptions

std::runtime_error

if runtime error occurred

getCurrentBackgroundLength()

virtual float voicesdk::SpeechSummaryStreamOpus::getCurrentBackgroundLength ( ) const

pure virtual

Method for retrieving current background length (length of a continuous non-speech segment starting on the last detected speech frame)

Returns

current background length in milliseconds

getSpeechEvent()

virtual SpeechEvent voicesdk::SpeechSummaryStreamOpus::getSpeechEvent ( )

pure virtual

Retrieves a single speech event from output FIFO queue. Use hasSpeechEvents() to check if there is available speech event.

Returns

A single speech event

Exceptions

std::runtime_error

if runtime error occurred

getTotalSpeechInfo()

virtual SpeechInfo voicesdk::SpeechSummaryStreamOpus::getTotalSpeechInfo ( ) const

pure virtual

Retrieves total accumulated speech info.

Returns

speech info

getTotalSpeechSummary()

virtual SpeechSummary voicesdk::SpeechSummaryStreamOpus::getTotalSpeechSummary ( ) const

pure virtual

Retrieves total accumulated speech summary.

Returns

speech summary

hasSpeechEvents()

virtual bool voicesdk::SpeechSummaryStreamOpus::hasSpeechEvents ( ) const

pure virtual

Checks if there are available speech events in output queue.

Returns

true if there is available speech event, false otherwise
