Be careful about the legal implications of using Google's TTS in your system. There are a few discussions on Google Groups (e.g. http://goo.gl/TvRVR) about the possibility of using Google's TTS for applications other than just Google Translate on the web, and there's a Google employee (DeWitt) saying that there are no Terms of Service (ToS), nor an official API for their TTS system, so that you should abide by their general ToS, and that "[TTS wasn't] designed for internal usage only, will likely change or break over time, and thus shouldn't be accessed by external developers"

Subject: Re: [Freeswitch-users] Is Anyone Using Google TTS?

I have to wonder if Google thinks 10-20 lookups per second from a single client is a "light/medium" load. That's 36K - 72K lookups per hour. If I were you I would tcpdump the traffic and see what Google is "really" sending back. I doubt that Google cares about the distinction between a browser and other types of clients.

Yes, I too can confirm that others are using this reliably.

What more can you tell us about your problem?

Best,

Hello,

Just wanted to find out when you say "reliably" is this being used in production on a relatively small/medium load, like maybe 10-20 look-ups/translations per second? The last I checked (about 4-5 mths ago) after about 10 or so (can't remember the exact number) Google throws out a Captcha as a challenge. Now, that could also be since I was doing this over a web-browser. Does it change or doesn't have that limitation when using mod_shout in freeswitch?

Thanks so much
