Detailed Description

In-process native CPU transcription backend used as the product-owned reference runtime.

The Phase 5 reference path is intentionally narrow and deterministic. It owns its model parsing, session state, and transcript emission without exposing any third-party runtime handles to the rest of the app.

Constructor & Destructor Documentation

CpuReferenceTranscriber()

CpuReferenceTranscriber::CpuReferenceTranscriber	(	TranscriberConfig	config,
		std::shared_ptr< const TranscriptionModelHandle >	model
	)

Creates a mutable native CPU session from a loaded model handle.

Parameters

config	Runtime configuration copied into the session.
model	Shared immutable model handle created by the native CPU engine.

Member Function Documentation

backendName()

QString CpuReferenceTranscriber::backendName ( ) const

overridevirtual

Returns the backend identifier for this live session.

Returns

Short backend name used for logs and diagnostics.

Implements TranscriptionSession.

backendNameStatic()

static QString CpuReferenceTranscriber::backendNameStatic ( )

static

Returns the stable backend identifier used in diagnostics.

Returns

Product-owned backend name for the CPU reference runtime.

cancel()

TranscriptUpdate CpuReferenceTranscriber::cancel ( )

overridevirtual

Requests cooperative cancellation of any active decode.

Implementations should stop in-flight backend work best-effort without using thread interruption.

Implements TranscriptionSession.

capabilitiesStatic()

static BackendCapabilities CpuReferenceTranscriber::capabilitiesStatic ( )

static

Returns static capability metadata for the native CPU runtime.

Returns

Engine-owned capability snapshot.

createSession()

static std::unique_ptr< TranscriptionSession > CpuReferenceTranscriber::createSession ( TranscriberConfig  config, std::shared_ptr< const TranscriptionModelHandle >  model  )

static

Creates a mutable session from a generic app-owned model handle.

Parameters

config	Runtime configuration copied into the session.
model	Shared immutable model handle.

Returns

Session on success, otherwise nullptr when the model type is incompatible.

diagnosticsStatic()

static RuntimeDiagnostics CpuReferenceTranscriber::diagnosticsStatic ( )

static

Returns static runtime diagnostics for the native CPU runtime.

Returns

Engine-owned diagnostic description.

finish()

TranscriptUpdate CpuReferenceTranscriber::finish ( )

overridevirtual

Flushes the current utterance and emits any final transcript events.

Returns

Final transcript events or a structured runtime failure.

Implements TranscriptionSession.

loadModelHandle()

static std::shared_ptr< const TranscriptionModelHandle > CpuReferenceTranscriber::loadModelHandle ( const TranscriberConfig &  config, RuntimeError *  error = nullptr  )

static

Loads an immutable native CPU model handle from a validated package.

Parameters

config	Runtime configuration copied into the handle.
error	Optional output for model validation or load failures.

Returns

Shared immutable model handle on success.

pushAudioChunk()

TranscriptUpdate CpuReferenceTranscriber::pushAudioChunk ( const AudioChunk &  chunk )

overridevirtual

Ingests one normalized audio chunk into the live session.

Parameters

chunk

Product-owned normalized audio chunk.

Returns

Any transcript events emitted while ingesting the chunk.

Implements TranscriptionSession.

warmup()

bool CpuReferenceTranscriber::warmup ( RuntimeError *  error = nullptr )

overridevirtual

Performs optional backend warmup for this session.

Parameters

error

Optional destination for a structured failure reason.

Returns

true if the session is ready for transcription, otherwise false.

Implements TranscriptionSession.
