Description

G10L encompasses techniques for analyzing, synthesizing, and processing speech and audio signals, including speech recognition systems that identify and interpret spoken content, as well as voice processing methods such as speaker identification and emotion detection. This subclass also covers audio and speech coding/decoding technologies that compress and decompress voice data for transmission or storage, enabling efficient communication and multimedia applications. The classification includes acoustic feature extraction, signal processing algorithms, and computational methods applied to speech and voice signals, but excludes general audio signal processing unrelated to speech (covered under G10H and related classes) and non-acoustic speech analysis such as written text processing.

Scope Notes

Glossary: speech definite vocal sounds that form words to express thoughts and ideas. voice voices sounds generated by vocal chords or synthetic versions thereof. audio signal audio signals of or relating to humanly audible sound, meant to include speech, voice, music, silence or background noise, or any combinations thereof. | Limiting references: Devices for the storage of speech signals Static stores Encoding of compressed speech signals for transmission or storage
