how to convert text to speech using Twillio API in java & RestAPI

enter code hereWhen application initiates a call to the Twilio API, for example via the CallFactory.create method, Twilio will send your request to a URL that is expected to return a TwiML response.

The Say verb converts text to speech that is read back to the caller. is useful for development or saying dynamic text that is difficult to pre-record.

Another option for responding with TwiML is via the TwiMLResponse class, which is available in the com.twilio.sdk.verbs package.

// Use your account SID and authentication token instead
// of the placeholders shown here.
String accountSID = "your_twilio_account";
String authToken = "your_twilio_authentication_token";

// Create an instance of the Twilio client.
TwilioRestClient client;
client = new TwilioRestClient(accountSID, authToken);

// Retrieve the account, used later to create an instance of the CallFactory.
Account account = client.getAccount();

// Use the Twilio-provided site for the TwiML response.
String Url="http://twimlets.com/message";
Url = Url + "?Message%5B0%5D=Hello%20World";

// Place the call From, To and URL values into a hash map. 
HashMap<String, String> params = new HashMap<String, String>();
params.put("From", "NNNNNNNNNN"); // Use your own value for the second parameter.
params.put("To", "NNNNNNNNNN");   // Use your own value for the second parameter.
params.put("Url", Url);

// Create an instance of the CallFactory class.
CallFactory callFactory = account.getCallFactory();

// Make the call.
Call call = callFactory.create(params);

• sample code to generating the TWIML using TwiMLResponse class using inputMsgString :

  TwiMLResponse twiml = new TwiMLResponse(); Say say = new Say( inputMsgString); twiml.append(say); msgAsXML = twiml.toXML();
