+ * Because of the recurring voice cutout issues (SL-15072) we are going to try
+ * to disable the automatic VAD (Voice Activity Detection) and set the associated
+ * parameters directly. We will expose them via Debug Settings and that should
+ * let us iterate on a collection of values that work for us. Hopefully! 
+ *
+ * From the VIVOX Docs:
+ *
+ * VadAuto: A flag indicating if the automatic VAD is enabled (1) or disabled (0)
+ *
+ * VadHangover: The time (in milliseconds) that it takes
+ * for the VAD to switch back to silence from speech mode after the last speech
+ * frame has been detected.
+ *
+ * VadNoiseFloor: A dimensionless value between 0 and 
+ * 20000 (default 576) that controls the maximum level at which the noise floor
+ * may be set at by the VAD's noise tracking. Too low of a value will make noise
+ * tracking ineffective (A value of 0 disables noise tracking and the VAD then 
+ * relies purely on the sensitivity property). Too high of a value will make 
+ * long speech classifiable as noise.
+ *
+ * VadSensitivity: A dimensionless value between 0 and 
+ * 100, indicating the 'sensitivity of the VAD'. Increasing this value corresponds
+ * to decreasing the sensitivity of the VAD (i.e. '0' is most sensitive, 
+ * while 100 is 'least sensitive')
