TTS Sonos

[hayabusachris 1]

Hay has anyone any idea why the text to speak is no longer working - about 8 weeks ago it needed an adjustment in the LUA code but again it has stopped?

I also tested google translator directly from a http connection without involving Sonos to discard Google malfunction and I got not errors.

You may get the "excesive use from your IP" message if the http request is invalid.

I can get through (no errors), still having the same issue playing TTS commands....

That confirms my fears. Google is not the problem. Most likely the problem is that the new Sonos 5.5 release has implemented some changes in the API and our virtual device must be updated accordingly in order to build the streams in the way the new API expects.

So, we need the VD architect here... Krikroff, do you feel like having a quick glance to the new Sonos release?

actually google is the problem.

I think they limited it to 2 or 3 requests a day.

At least for me after 2 or 3 requests with a browser the site basicly disappears (404 error)

Doesn't matter if your request is valid or invalid

Which browser are you using?

If you try to pass a stream request to Google Translator using UTF-8 (my second example) over MS Internet Explorer 11 you will be rejected to the well known blocking page. With this browser you must use Non UTF-8 code (my first example)

If you use Google Chrome or last version of Mozilla Firefox, both ways should work... for an unlimited number of times.

Confirmed, works unlimited times in Chrome for me.

i get this aswell.

when i try and click on the link using my mobile data signal it works all the time.

this suggests that it is a google issue registering requests from the same IP

Well, meanwhile someone finds the way to adapt the scene to Sonos 5.5 release, or Sonos releases a new version that performs like the old one, I have found a way to overcome the problem, changing only three lines of code. I have tested it for 48h and it is working fine.

The idea is as follows:

Since, like I posted somewhere above in this thread, when TTS stops working, if you remove the "ie=UTF-8" character set definition in the Sonos.PlayTTS function of the Virtual Device (main loop), the TTS starts working again... until something else (internet radio or locally stored files) is played through Sonos. Then it fails to play TTS again, until you replace back "ie=UTF-8".

Unfortunately, I have not found a simple way to verify automatically if the message actually plays or not. Therefore, what I have done is a small modification in the code that sends both requests to the API: one with the standard charset, and a second one with the UTF-8.

Since only one of those will work at a time, Sonos will not repeat the message.

The only drawback I have seen so far is that the messages take a little longer to pass through, and there may be one or two more interruptions in the music than expected but… it works.

For those who are also struggling with the stream examples I posted before, this workaround may not work. It seems that these users have also some networking issue.

 

These are the modifications to be done in the virtual device’s main loop script:

 

In Sonos.PlayTTS function:

That's it. Welcome back Sonos TTs. I hope it works for you.

Although I hate the only Spanish voice available at Google, it is good to have the announcements back

Hello Brik, This workarround looks great. unfortunately my LUA code in thee VD looks different ;-(

[Brick 13]

I know there are several flavours of Krikoff's VD but I thought that lua basics were similar in all of them. Are you using on of those or do you have a complete different solution developed  by someone else?

[KristianO 15]

Tested and works perfectly! Thanks!

[Hoggle 1]

Is your solution still working?

[Brick 13]

To be honest, I don't know. I found out several weeks ago that Krikoff updated his VD using an alternative TTS engine, different to Google Translator and I switched my scenes to that solution.
