• Tensorflow C code is walk through is done
• Rust \ C mapping is almost done
• Issue is difference is Sonogram FFT

Closer need a few more days + Blog posts

Have set up a demo with custom model retraining at: Colab notebook

I recorded a dataset of 4 commands (up, down, left, right) in Estonian (yles, alla, vasak, parem), 10 samples each, and retrained the microspeech model with it (87% performance).

The format of data for input is currently:

• four folders for up/down/left/right wav files
• one folder for background noise
• some folders for “other” phrases, from speech commands dataset
  then tar gzip the files into an archive and upload to a server. The notebook takes as input link to the tar.gz file

@meelislootus, can this issue be closed now the microspeech Rune and DSP proc blocks are working? If so, we can probably also close #96.
