betterclever commented 7 years ago

Already tested CMU Sphinx (Pocketsphinx) - Issues -

  1. Slow recognition.
  2. Not easy to train via Audio Samples (Like we train Google Assistant: by speaking "Ok Google" 3 times)
  3. False positives on slow dictionary.
  4. Negative results/ wrong detection on large dictionary.

Currently Testing: Python Hotword Recogniton (https://github.com/sakethgsharma/HotWordDetection) Advantages:

  1. Training based recognition
  2. Fairly correct results if training done right.

Problems being faced:

  1. False positive results sometimes.
  2. Figuring out a way for continuous detection.
  3. Error while detection after training sometimes. (Will update with logs)

Pertaining to problems in Python Hotword Recognition Library, I switched back to Pocketsphinx for hotword. After, some adjustments in kws threshold value, the detection is fine now (mostly). Yet, to eradicate false positive results though.
