VAD Flag

VAD Flag takes the Modulation Index and compares it to a threshold value. If the threshold value is met for the designated amount of time, the output flag is set high, otherwise it is low.

Input:

• Unordered List ItemModulationIndex

Output

• Unordered List ItemConditionFlag: 0 or 1 output determining if speech is present or not

Parameter Control:

• Threshold: dB value for comparison with Modulation Index
• Count: Time value in (ms) for condition to be met before setting flag high
