Plivo charges for automatic speech recognition based on the usage of Plivo’s speech recognition engine. For every GetInput XML execution, charges are applied based on the duration of the speech analyzed.
Charges are computed per 15-second pulse. For example, if speech is recognized for 35 seconds, the account would be billed for 45 seconds (15 * 3) of speech.
Charges apply only to speech input detection. DTMF input detection with GetInput XML is not charged. So, if you’re using GetInput with inputType set to "dtmf," you will not be charged.
