offline example doesn't recognise speech

[hamishfagg]

Hi there,

I have just received my respeaker and I am testing the example offline_voice_assistant.py script here.
I have set the wake up word to alexa as a test but the same thing happens regardless. I have turned the mic volume up in alsa and I am still unable to get this script to recognise a single word - I've tried saying things ranging from "hello" to full scentences. Below is the output from the script:

Any ideas? Thanks

The offline example only recognizes three keyword. It's in https://github.com/respeaker/respeaker_python_library/blob/master/respeaker/pocketsphinx-data/keywords.txt

You can add new words to keywords.txt and dictionary.txt. You can find the words in https://github.com/respeaker/pocketsphinx-data/blob/master/dictionary.txt

Hi,

Are we able to get some documentation on exactly what is required for respeaker to recognise new words using microphone.recognise() ?

I have replaced the dictionary file with the one that comes with pocketphinx and mic.recognise() will still only recognise "play music".

@IVData you just have to install the package again
