pyannote or WeSpeaker: which speaker tool to pick
These are not really competitors but neighboring layers of the same job, and they are often used together: one of the WeSpeaker models is built into pyannote 3.x. pyannote answers who spoke and when, splitting a recording by speaker, usually paired with speech recognition; the weights are issued after a short form on HF, under MIT for 2.x, 3.0 and 3.1 and CC-BY 4.0 for community-1. WeSpeaker is the voiceprint side: compare two recordings to tell whether it is the same person, plus help with speaker splitting; the code is Apache 2.0, the weights CC-BY 4.0 and Apache 2.0. Both run on a CPU. The catalog lists WeSpeaker for banking, insurance and security teams, and pyannote for call centers, legal, HR and podcasts.
