Speaking Multiple Languages

When working with multinational callers, American English might not be the language or accent you want to use for your application's prompts. Tropo provides many different voice options to choose from, and it's all controlled using the voice parameter:

require 'tropo-webapi-ruby'
require 'sinatra'

post '/index.json' do
  t =
  t.say "Hello, how are you?", :voice => "kate"

var http = require('http');
var tropo_webapi = require('tropo-webapi');

var server = http.createServer(function (request, response) {
	var tropo = new TropoWebAPI();

	// (value, as, name, required, voice)
	tropo.say("Hello, how are you?.", null, null, null, null, "kate");


require 'tropo.class.php';

$tropo = new Tropo();
$tropo->say("Hello, how are you?", array("voice" => "kate"));

from itty import *
from tropo import Tropo

def index(request):

    t = Tropo()
    t.say("Hello, how are you?", voice = "kate")
    return t.RenderJson()

run_itty(server='wsgiref', host='', port=8888)
               "value":"Hello, how are you?",

The previous example shows how to speak using Kate, a British English voice. We also have Daria, Magnus, Karen and quite a few others ready for you. A complete list appears below.

Language Female Voice Male Voice
English (UK) Kate, Serena (Default) Daniel, Oliver
English (US) Evelyn, Zoe

If you need to recognize voice input as well, you probably need to define which language Tropo is listening for using the recognizer parameter, which we cover next.
