问题
I've created a Twilio application that involves using Twilio's TwimL <Say> command to read off a list of numbers that constitute an ID that the user has previously input (e.g., 3638194746219190 or something along those lines). Since it's a long list of numbers, I have the application read back the list of numbers to confirm that the user has input them correctly. Since it's dynamic, I can't pre-record it--it has to be with <Say>, but Twilio reads it back way too quickly.
I currently have the numbers played back with spaces and commas between them to slow them down, for example: '3, 6, 3, 8, 1, 9, 4, 7, 4, 6, 2, 1, 9, 1, 9, 0', and that has helped a little bit, but it still reads the list back way too quickly.
Do you know how to force Twilio's <Say> command to slow down its text-to-speech playback even further?
回答1:
You could try using periods, e.g. 1. 2. 3. 4. 5. 6. 7. 8. 9.
回答2:
You can add multiple commas or periods and it'll increase the pause time. You may also consider adding longer breaks every X numbers so it has a more natural cadence to it.
3,,,6,,,3,,,8,,,,,,,1,,,9,,,4,,,7,,,,,,,4,,,6,,,2,,,1

You can add a <Pause> verb to pause execution for a number of seconds. The documentation is here: http://www.twilio.com/docs/api/twiml/pause
There's more information about generating pauses in TwiML at this question: How can I generate a half second pause in TwiML?
