From the silence-softest /a/ trials:
- Select a 1 second segment of silence, put it in Praat and get intensity.

From the silence-softest /a/ trials:
- Select a 1 second segment of softest /a/ and get intensity
|

Calculate SNR by subtracting the silence intensity from the softest /a/ intensity
(Softest /a/)dB – (silence)dB = SNR
Calculate it in the Redcap Connected Speech instrument.
Ideally SNR is between 20db and 40db.
If SNR is within 20dB-25dB, the session should not be completed. **(Look below at solutions) |
 
Example:softest /a/ 60.34dB - silence 29.98dB = 30.36dB
