2 1) The <head> information in this page is significant, should be uniform

334 Use the <code>chrome.experimental.tts_engine</code> module to
335 implement a text-to-speech (TTS) engine using an extension. If your
336 extension registers using this API, it will receive events containing
337 the intended utterance and other parameters when any extension or packaged
338 app uses the
339 <a href="experimental.tts.html">experimental.tts</a>
340 module to generate speech. Your extension can then use any available
341 web technology to synthesize and output the speech, and send events back
342 to the calling function to report the status.
343 </p>
344
345 <p class="note"><b>Give us feedback:</b> If you have suggestions,
346 especially changes that should be made before stabilizing the first
347 version of this API, please send your ideas to the

349 group.</p>
350
351 <h2 id="overview">Overview</h2>
352
353 <p>To enable this experimental API, visit
354 <b>chrome://flags</b> and enable <b>Experimental Extension APIs</b>.
355
356 </p><p>An extension can register itself as a speech engine. By doing so, it
357 can intercept some or all calls to functions such as
358 <a href="experimental.tts.html#method-speak"><code>speak()</code></a> and
359 <a href="experimental.tts.html#method-stop"><code>stop()</code></a>
360 and provide an alternate implementation.
361 Extensions are free to use any available web technology
362 to provide speech, including streaming audio from a server, HTML5 audio,
363 Native Client, or Flash. An extension could even do something different
364 with the utterances, like display closed captions in a pop-up window or
365 send them as log messages to a remote server.</p>
366
367 <h2 id="manifest">Manifest</h2>
368
369 <p>To implement a TTS engine, an extension must first declare all voices
370 it provides in the extension manifest, like this:</p>
371
372 <pre>{
373 "name": "My TTS Engine",
374 "version": "1.0",
375 <b>"permissions": ["experimental"],
376 "tts_engine": {
377 "voices": [
378 {
379 "voice_name": "Alice",
380 "lang": "en-US",
381 "gender": "female",
382 "event_types": ["start", "marker", "end"]
383 },
384 {
385 "voice_name": "Pat",
386 "lang": "en-US",
387 "event_types": ["end"]
388 }
389 ]
390 },</b>
391 "background_page": "background.html",
392 }</pre>
393
394 <p>An extension can specify any number of voices.</p>
395
396 <p>The <code>voice_name</code> parameter is required. The name should be
397 descriptive enough that it identifies the name of the voice and the
398 engine used. In the unlikely event that two extensions register voices
399 with the same name, a client can manually specify the extension id to

400 receive speech calls.</p>
401
402 The <code>gender</code> parameter is optional. If your voice corresponds
403 to a male or female voice, you can use this parameter to help clients
404 choose the most appropriate voice for their application.
405
406 <p>The <code>lang</code> parameter is optional, but highly recommended.
407 Almost always, a voice can synthesize speech in just a single language.
408 When an engine supports more than one language, it can easily register a
409 separate voice for each language. Under rare circumstances where a single
410 voice can handle more than one language, it's easiest to just list two
411 separate voices and handle them using the same logic internally. However,
412 if you want to create a voice that will handle utterances in any language,
413 leave out the <code>lang</code> parameter from your extension's manifest.
414
415 Finally, the <code>event_types</code> parameter is required if the engine can
416 send events to update the client on the progress of speech synthesis.
417 At a minimum, supporting the <code>'end'</code> event type to indicate
418 when speech is finished is highly recommend, otherwise it's impossible
