Super, glad that helped. You can increase or decrease OEPocketsphinxController’s property vadThreshold. Higher settings will exclude more noise (but if it’s too high, it will exclude non-noise speech) and lower settings will allow more noise. I am still searching for the correct default setting for vadThreshold since it is part of the brand-new area of the framework, so your feedback on that is useful. OpenEars’ current default value is 1.5 and CMU Sphinx uses the default value 2.0 (but I thought it was excluding a bit too much real speech).
