Speech Recognition Patent Classification
Speech technology concentrates in a single subclass: G10L covers speech analysis, speech synthesis, speech recognition and audio coding. Voice assistants, transcription engines and text-to-speech systems all classify here.
Modern voice products combine G10L with the machine-learning models of G06N; language understanding beyond the audio signal often adds codes from natural-language processing in G06F 40/00.
