Voice Recognition Options

It's possible to set the expected spoken language, for recognition by setting the following variable in config.php to the culture variant. The default is en-US, which is US English.

Use the this chart to find the code of your preference https://www.twilio.com/docs/api/twiml/gather#languagetags.

static $gather_language = "en-US";

You can also set some expected words or hints, to help the voice recognition engine along. Use the setting by separating words with commas. You can use phrases as well.

Each hint may not be more than 100 characters (including spaces). You can use up to 500 hints.

static $gather_hints = "";
