    // basic usage
    TTS.speak('hello, world!', function () {
            alert('success');
        }, function (reason) {
            alert(reason);
        });
    
    // or with more options
    TTS.speak({
            text: 'hello, world!',
            locale: 'en-GB',
            rate: 0.75
        }, function () {
            alert('success');
        }, function (reason) {
            alert(reason);
        });
}, false);

Tips: speak an empty string to interrupt.

API Definitions

The onfulfilled callback will be called when the speech finishes, and the onrejected callback (Windows Phone only) will be called when an error occurs.

If the API is invoked when it's still speaking, the previous speaking will be canceled immediately, but the onfulfilled callback of the previous speaking will be called when it stops.

declare module TTS {
    interface IOptions {
        /** text to speak */
        text: string;
        /** a string like 'en-US', 'zh-CN', etc */
        locale?: string;
        /** speed rate, 0 ~ 1 */
        rate?: number;
    }

    function speak(options: IOptions, onfulfilled: () => void, onrejected: (reason) => void): void;
    function speak(text: string, onfulfilled: () => void, onrejected: (reason) => void): void;
}
