Adding basic SSML support to Polly

[dwm66]

I recognized that the API basically could support SSML for AWS Polly.
The phrase of course has to encode all the SSML tags, so that a phrase like
<speak><prosody rate="90%">Hello</prosody></speak>
has to be sent as
http://mysonos:5005/Office/say/%3Cspeak%3E%3Cprosody%20rate%3D%2290%25%22%3EHello%3C%2Fprosody%3E%3C%2Fspeak%3E

Nevertheless, the phrase is sent correctly to AWS, the only "showstopper" is that in the AWS API call, the TextType is set to text.

I now added a few simple lines in the aws-polly.js provider, detecting the leading and ending "<speak>" tags in an SSML phrase and setting the TextType to "ssml" accordingly.

Hello, great thing, unfortunately it doesn't work for me:
http://192.168.0.96:5005/Wohnzimmer/say/Einen wunderschönen Abend! <prosody rate="slow"> Es ist jetzt Zeit mit der Zeit zu üben.</prosody>/Hans/30
Also
http://192.168.0.96:5005/Wohnzimmer/say/<speak>Jeden Morgen wenn ich aufwache, <prosody rate="slow"> spreche ich sehr langsam bis ich meinen ersten Cafe trinke. </prosody></speak>/Hans/30
unfortunately does not work. Yes, the typo is fixed to "TextType" and the service is restarted.
What am I doing wrong?
kr, mxa

Edit, for information only, this works perfectly without SSML.

Hello,
the characters <>/ .., are reserved characters, which must not be passed in the url.
The Sonos API tries to decode it, which does not work.

Therefore, you must use URL encoding to pass a SSML type phrase.
Please see: https://www.urlencoder.io/learn/

In order to encode your phrase, you can use something like https://www.urlencoder.org/
or - if calling it by Javascript, the encodeURI function.

Your example should work, if you call it like

http://192.168.0.96:5005/Wohnzimmer/say/%3Cspeak%3EJeden%20Morgen%20wenn%20ich%20aufwache%2C%20%3Cprosody%20rate%3D%22slow%22%3E%20spreche%20ich%20sehr%20langsam%20bis%20ich%20meinen%20ersten%20Cafe%20trinke.%20%3C%2Fprosody%3E%3C%2Fspeak%3E/Hans/30

Hi,
my browser FF encoded the respective url too, but that's wrong. Thanks to your explanation, I now use the JavaScript function as follows:

function encodemeins () { var url = '<speak>Jeden Morgen wenn ich aufwache, <prosody rate="x-slow"> spreche ich sehr langsam bis ich meinen ersten Cafe trinke. </prosody></speak>'; var url_enc = encodeURIComponent(url); var res = "http://192.168.0.96:5005/Wohnzimmer/say/"+ url_enc + "/Hans/30"; console.log(res); };

That is exactly how I imagined it to be, thank you for your work!

Hi,
I just tested the changes of dwm66 to announce either radio station name or artist, title. Works great with these short text inputs. Didn't test it with longer texts. These tags were used in my example: speak, break, prosody.
