Core data structures for audio transcription

Import

from cjm_transcription_plugin_system.core import (
    AudioData,
    TranscriptionResult
)

Classes

@dataclass
class AudioData:
    "Container for audio data and metadata."
    
    samples: np.ndarray  # Audio sample data as a numpy array
    sample_rate: int  # Sample rate in Hz (e.g., 16000, 44100)
    duration: float  # Duration of the audio in seconds
    filepath: Optional[Path]  # Audio file path
    metadata: Dict[str, Any] = field(...)  # Additional metadata

@dataclass
class TranscriptionResult:
    "Standardized transcription output."
    
    text: str  # The transcribed text
    confidence: Optional[float]  # Overall confidence score (0.0 to 1.0)
    segments: Optional[List[Dict]] = field(...)  # List of transcription segments with timestamps and text
    metadata: Optional[Dict] = field(...)  # Transcription metadata

Transcription Plugin Interface (plugin_interface.ipynb)

Domain-specific plugin interface for audio transcription plugins

Import

from cjm_transcription_plugin_system.plugin_interface import (
    TranscriptionPlugin
)

Classes

class TranscriptionPlugin(PluginInterface):
    """
    Transcription-specific plugin interface.
    
    This extends the generic PluginInterface with transcription-specific
    requirements like supported audio formats and the execute signature.
    
    All transcription plugins must implement this interface.
