I am asking the caller to speak a 12 digit number. In the built-in voice grammar, I have it set to use "digits" and at exactly 12 digits long. The behavior I expect is when the caller finishes speaking 12 digits, the IVR will stop accepting additional digits. However, you can continue to speak as many digits as you want, even though the grammar is only looking for exactly 12 digits.

When using DTMF, once you enter the 12th digit, the IVR no longer accepts further inputs, and moves on to the next node. But for voice, it continues to listen even though the caller has clearly finished speaking 12 digits.

Is there a way for this to behave the same way as DTMF and stop allowing additional digits beyond 12? Or is it just the way it is?

Hi.

Did you test the app without changing the grammar on the platform (the EP) ?
