How to blocking audio playback?

[hansipete]

Hello,

first of all - great library. Really enjoy it! Thank you @schreibfaul1 for the effort you put in

I my project I need feedback sounds and text2speech that plays just before something else happens, e.g. a stream starts. My approach to this is something like this.

bool speechFinished = false;

void blockingTextToSpeech(char *txt)
{
    audio.connecttospeech(txt, "de");
    speechFinished = false;
    while (!speechFinished)
    {
        audio.loop();
    }
}

void audio_eof_speech(const char *info)
{
    speechFinished = true;
}

Somewhere in my program I can use blockingTextToSpeech("Now playing station xy") and it will wait for the audio to be finished before proceeding. Is this the "right" way to do it?

Tschüss,
Hans

Hello Hans,
GoogleTTS is not a reliable service. If it is called up too often, Google suspects a bot and blocks the IP address. In addition, the text is limited in length. I wouldn't run the audio.loop() in a while loop, especially since no time is wasted when there's nothing to do. Using the speechFinished flag is okay.

I'm also playing with Googles TTS Audio features.

Hans did your SpeechFinished flag work the way you wanted it?

Schreibfaul1 - What is the limit on the text we can send? Ideally alittle more text would be ideal to get a short weather report created on one connection.

Currently I can send about 200 words before it errors out. Is that a Google issue or the text variable size setting limitation?

I do remember that it worked allright. Go for it! :-)

GoogleTTS actually has a limitation, only short sentences will work. MaryTTS could be the solution. Please try audio.connecttomarytts('Hello World', 'en_GB', 'dfki-spike'); I don't know where the limit is, but longer texts are possible.

I will give MaryTTS a try then. Maybe that's the ticket even though it's voice does not sound near as normal as Googles TTS for shorter sentences.

I'll give it a go in the near future and report back.
