Can the wakeword response be changed from a tone to a phrase?
MarkMLl
The âwakeword response toneâ is a audio-file located at mycroft-core/mycroft/res/snd/start_listening.wav
You can replace that file with your own recording of a phraseâŚ
Thanks for that. So I could use a .wav of âYes, Milady?â or whatever, but I canât trigger text-to-speech output which would fit seamlessly with the rest of the dialogue.
Yes, the file should be wav-format, 16bit, stereo, 44100Hz sampling rate.
You could trigger TTS output by utterance âsay yes miladyâ or from command-line mycroft-speak and record the output to a wav-file.
Being able to redirect that output to a file would be quite a useful debugging facilityâŚ
Mycroft temporarily saves tts ouput (at least when using Google-TTS) in folder /tmp/mycroft/cache/tts/.
Type say yes milady in the mycroft-cli-client and watch out for the latest file in the tmp folder, the .mp3-file with the latest file-stamp should be the one you are looking for (the last entry of /var/log/mycroft/audio.log should give you the file-name as well). Convert that file to .wav and you are setâŚ

Thanks, Iâll check and report back. Iâd expect Socks to be able to handle the conversion.
That works, and with the default (Mimic) TTS itâs already a .wav file. The one thing Iâd caution is that the cached files donât get their timestamps touched, so if itâs the second time in a session youâve asked it to say something it might not be the most recent file.
One additional thing Iâd throw in is that a slightly longer file (similar to the âyes miladyâ I used as an example) might possibly be messing something up related to echo suppression: asking e.g. âwhere are youâ intermittently applies lots of âreverbâ to the answer⌠Iâve not yet checked whether this is fixed by a restart.
Thatâs interesting to hear about the âreverbâ, let us know if it continuesâŚ
It happened several times but a restart apparently fixed it. Iâll advise if it happens again.

OK, this is great fun. Wakeword acknowledgement is set to âYes your excellencyâ (nod to one of the Niven/Pournelle books).
This is the result of asking it âwhatâs 22 divided by 7â asked a couple of times:
yes you like scentsy whatâs 22 / 7
22/7 (irreducible)
yes your excellency whatâs 22 / 7
22/7 (irreducible)
Several times Iâve got âncâ at the start of a command, suggesting that the timing of the start of command capture is a little erratic.
As in itâs sometimes catching the end of the âexcellencyâ as the start of your utterance?
The precise timing of when to start capturing an utterance is a bit of an art form. You donât want a big gap between the acknowledgement and when capture starts, but also even if the acknowledgement is just a noise like the default, it can throw out the automated mic leveling given that sound is being output from quite close to the microphone.
I suppose that this folds into what somebody was saying about echo cancellation since commercial devices are often playing music at the same time as theyâre expected to listen for a wakeword.
