STT - tips and tricks

Saving Transcriptions

You can enable saving of recordings to file, this should be your first step to diagnose problems, is the audio inteligible? is it being cropped? too noisy? low volume?

set "save_utterances": true in your listener config, recordings will be saved to ~/.local/share/mycroft/listener/utterances

If the recorded audio looks good to you, maybe you need to use a different STT plugin, maybe the one you are using does not like your microphone, or just isn't very good for your language

Individual Device

OVOS provides a list of public servers maintained by trusted community members, no account needed

For SBCs like the raspberry pi 3 or where minimum latency is desired it might be benefitial to offload STT and TTS to a more powerful server, such as a OVOS public server or a commercial service (google, amazon...)
