I wish I had something more constructive to say than 'wow, this is really cool' but, wow, this is really cool. I was saddened to see speech synthesis and speech generation (seemingly) punted from the Win8 WinRT APIs. And here you are doing it with a bit of Javascript.

iOS doesn't offer much in the realm of TTS either. Siri has such a good voice but there is no API to make your iPhone or iPad talk from your own app.

OpenEars has made a decent TTS engine (based on flite) but it is far from the top of the line engines offered by Acapela, Ivona, and NeoSpeech.

Sounds a lot like the old Talking Moose/Macintalk voice (1986):

Why does it pronounce Caligula as Caligul? And is it possible to input IPA into it?

chrischen• 14 years ago

It seems to ignore the -a in "sucka" too. Must be something with trailing As.

tiglionabbit• 14 years ago

It seems to be missing 'ly' as well.

Not working - Ubuntu Lucid, Firefox 13.0.1., no speakers - headphones.

Otherwise - excellent hack, can have many uses - marketing, e-commerce, people with disabilities, you name it.

How does this work? Does it use the audio tag and a data URI?

chewxy2• 14 years ago

The source is here[1]. It does use an audio tag in speakClient.js

Read through speakGenerator to see how the data is generated I guess

Not playing on Safari, Mac OS X 10.7.4

chewxy2• 14 years ago

Doesn't work on Firefox 13.01 on Ubuntu Precise. Works on Chromium 18.05.

Fun one: Speed - 115, Amplitude - 50, Pitch - 200, Text - "Never give up, never surrender"

katsuyan2• 14 years ago

A bit scary lol

mtgx• 14 years ago

Off-topic, but Ubuntu Software Center seems to be stuck on Chromium 18 for a while. Plus, for some reason there's no Chrome in the Software Center, although you can download it from Google in the browser (Chrome 20 now, and seems more stable than Chromium 18).

azakai2• 14 years ago

Works on Firefox 16 on Ubuntu.

Do you get an error in the web console (control-shift-k)?

ck2• 14 years ago

Works on Firefox 14 just fine.

Not friendly with Dolphin Browser on Android.

I will be adding this to my accessibility toolbox -- thanks for sharing this! A bit of a tangent -- does anyone have experience making their (single-page) web apps accessible (especially in the context of W3's "Web Content Accessibility Guidelines (WCAG) 2.0"): http://www.w3.org/TR/WCAG/)? If so, could you share a starting point/good-resource on troubleshooting some of the issues that arise?

Doesn't work with Flashblock enabled, which seems odd to me.

adrinavarro• 14 years ago

Works here for me with flash disabled in chrome settings. The code is an embedded audio with inline base64 data.

For those curious (I didn't know myself until researching some ideas for this API), Chrome has a built-in text-to-speech API (http://code.google.com/chrome/extensions/tts.html) for use in extensions and packaged web apps.

katsuyan2• 14 years ago

Nice! Sounds like this has higher quality though it's only available in chrome.

jfoster• 14 years ago

Note that the Chrome one is limited to Chrome browser extensions and packaged apps. For one reason or another it doesn't extend to hosted Chrome apps.

PsyGeek• 14 years ago

Doesn't work with Firefox in Arch Linux using kernel 3.3.7 -- odd.

syassami• 14 years ago

Works on Chrome - osx lion, you have to wait a good 15 seconds before sound starts though

unimpressive• 14 years ago

Not working in Ubuntu 11.10, Firefox 13.

Wow... http://speak-demo.herokuapp.com/javascripts/speakGenerator.j...

BaconJuice• 14 years ago

can someone explain to me what is going on in there? How are the words generated with this file?

radarsat1• 14 years ago

Hm, I guess that is compiled from http://espeak.sourceforge.net/ so the source might be a better starting point.

dharma1• 14 years ago

this is great!! Was looking for client side TTS for a rhyming hack a couple of weeks ago. Ended up piggybacking on Google's translator instead, which is great quality but is of course server side. http://helmicreative.com/lab/audio/rhyme.html

badragon• 14 years ago

GPL V3 so I would not take a chance with it.

azakai2• 14 years ago

If there is another speech generator with permissive licensing we can compile that one too.

martincerdeira• 14 years ago

It does not work on firefox 13.0.1

franze• 14 years ago

hiho

somethings in the air ... i coded a little project (also based on kripkens awesome speak.js) a month or so ago (in a little cabana in bolivia while i was travelling) http://lalo.li 100% client side, shareable text2speech voice messages

after some data crunching so far: people dont use it for anything useful, most traffic via facebook shares (of funny messages)
