speech-synthesis

问题 I'm trying to get the list of supported speech synthesis voices on iOS Safari. As per the API, I should be able to get an array of voices by calling: window.speechSynthesis.getVoices(); Sometimes this gives me list of voices, other times it doesn't. See the following jsfiddle: https://jsfiddle.net/sq7xf327/ If I open this on my iPhone 5 (iOS 8.1.3), I don't get back consistent results. Sometimes I get back all 37 voices, and other times I get returned 0 voices. If you keep on refreshing it

问题 In a webpage, I want a female voice to speak my texts. I tried to do this by following code. But still now male voice is talking. How can I arrange a female voice to talk my texts? Can anybody share me a correct code that works in Google Chrome. var voices = speechSynthesis.getVoices(); var msg = new SpeechSynthesisUtterance("Hello World!"); msg.default=false; msg.localservice=true; msg.lang = "en-GB"; msg.voice = voices[3].name; speechSynthesis.speak(msg); 回答1: The below code worked for me.

问题 This question already has answers here : Getting the list of voices in speechSynthesis (Web Speech API) (11 answers) Closed last month . Related to this text to speech question, I have the following code: First of all, I am not sure if this is the best way to write the code, because it is initializing, and then setting a listener to "call itself". (seems a little bit hacky). Second, although the listeners got "notified", the voices.length is still 0 . Nothing really happens with an array of

问题 I am trying out a simple example with Speechsynthesis. <script> voices = window.speechSynthesis.getVoices() var utterance = new SpeechSynthesisUtterance("Hello World"); utterance.voice = voices[4]; utterance.lang = voices[4].lang; window.speechSynthesis.speak(utterance); </script> But this gives an error that voices is undefined. I found that getVoices() is loaded async. I saw this answer and updated my code as shown below to use callback. <script> window.speechSynthesis.onvoiceschanged =

It'd print out 0 voices, and again print out 0 voices on my computer, but if I reload the page to start fresh, and change the last line to setTimeout(foo, 1000) , then the first line would print out 0 and second line, 87 . The number could even be changed to 66 or 33 and it worked, but I am not sure whether it depends

问题 When using the speak function in the Web Speech API, in Chrome the speaking stops abruptly after a few seconds, in the middle of the text given to it, in a seemingly random place (without reaching the end). This only happens in Chrome (works well on Firefox), tested on two different computers/systems. Have a look at this jsfiddle to see/listen: https://jsfiddle.net/fv9ochpq/ You can see that the SpeechSynthesis object .speaking flag stays on(true) after it stops speaking. I haven't seen any

问题 I recently implemented a basic web app which relied on Google's TTS URL to generate clear MP3 files for playback on the front end. This has since been subject to an additional security check, meaning I have had to update the code base to use alternative methods. One such alternative is javascript's speech synthesis API, i.e. SpeechSynthesisUtterance() and window.speechSynthesis.speak('...'). This works really well on my desktop and laptop but as soon as I use it on my iOS devices, the rate of
