speech-synthesis

Currently, I'm making a simple app where text is spoken using the speech synthesis API. I want to highlight the words (bold) as they are being spoken. I currently have a very basic implementation doing this using the 'onboundary' event. However, I'm wondering if there's a better/nicer way of doing it, as my implementation is based on a few presumptions. var words; var wordIdx; var text; var utterance = new SpeechSynthesisUtterance(); utterance.lang = 'en-UK'; utterance.rate = 1; window.onload = function(){ document.getElementById('textarea').innerText = 'This is a text area. It is used as a

I'm generating speech through Google Cloud's text-to-speech API and I'd like to highlight words as they are spoken. Is there a way of getting timestamps for spoken words or sentences? 来源： https://stackoverflow.com/questions/55320826/google-cloud-text-to-speech-word-timestamps

Web Speech API specification says: text attribute This attribute specifies the text to be synthesized and spoken for this utterance. This may be either plain text or a complete, well-formed SSML document. For speech synthesis engines that do not support SSML, or only support certain tags, the user agent or speech engine must strip away the tags they do not support and speak the text. It does not provide an example of using text with an SSML document. I tried the following in Chrome 33: var msg = new SpeechSynthesisUtterance(); msg.text = '<?xml version="1.0"?>\r\n<speak version="1.0" xmlns=

In both Chrome (v72, W10) and Opera, the following snippet very occasionally does not seem to run the attached end listener to the SpeechSynthesisUtterance , maybe 1 out of 50 times the snippet is run. (Sorry, in the original version of this, it could be reproduced much more easily - now, creating the utterance on button click looks to have made the bug much more rare) button.onclick = () => { console.log('start script'); button.disabled = true; const utt = new SpeechSynthesisUtterance('e'); utt.addEventListener('end', () => { console.log('end event triggered'); }); // just for debugging

This code is working but I'm only able to switch between the voices which came preInstalled in Microsoft Windows. These voices are "Microsoft David Mobile" and "Microsoft Zira Mobile". Later I installed "Microsoft Kalpana Mobile" and set it as the default Windows voice. But still I'm not able to switch to "Microsoft Kalpana Mobile". The code is- import pyttsx3 engine = pyttsx3.init() voices = engine.getProperty('voices') engine.setProperty('voice', voices[0].id) #changing index changes voices but ony 0 and 1 are working here engine.say('Hello World') engine.runAndWait() Only 0 and 1 are

The Speech Synthesis API allows text-to-speech functionality in Chrome Beta. However, results from TTS requests are automatically played by the browser. How do I access the audio results for post-processing and disable the default behavior of the API? There is no standard audio output for the TTS system and that seems quite intentional so it is unlikely to change anytime soon. To understand why, you can look at the other side of this interface where a browser extension can act as a TTS Engine and provide the voices the client can use: Being a valid TTS Engine accessible by this API in chrome

I'm using the Speech Synthesis API on Google Chrome v34.0.1847.131. The API is implemented in Chrome starting in v33. The text-to-speech works for the most part, except when assigning a callback to onend . For instance, the following code: var message = window.SpeechSynthesisUtterance("Hello world!"); message.onend = function(event) { console.log('Finished in ' + event.elapsedTime + ' seconds.'); }; window.speechSynthesis.speak(message); will sometimes call onend and sometimes not call it. The timing appears to be completely off. When it does get called, the printed elapsedTime is always some
