There is a type in NumberToText.h:

Line 80:
const char* second[10] = {"", "TEN", "TWENTY", "THIRTY", "FORTY",

...should be:
const char* second[10] = {"", "TEN", "TWENTY", "THIRTY", "FOURTY",

Good day! I am trying to get your Talking Clock to work. I'm using platformio with the following platformio.ini file:

[platformio] description = Audio Example default_envs = esp32dev

[env:esp32dev]
platform = espressif32 ;https://github.com/platformio/platform-espressif32.git
board =lolin_d32 ; esp32dev
framework = arduino
lib_deps = https://github.com/pschatzmann/arduino-audio-tools
https://github.com/pschatzmann/arduino-simple-tts
https://github.com/pschatzmann/arduino-libhelix

build_flags = -DCORE_DEBUG_LEVEL=5 -Wno-unused-variable -Wno-unused-but-set-variable -Wno-unused-function -Wno-format-extra-args
monitor_speed = 115200
monitor_filters = esp32_exception_decoder


My out stream is to a Pmod I2S2, using this config:

// start I2S Serial.println("starting I2S..."); auto config = i2s.defaultConfig(RXTX_MODE); config.sample_rate = 44100; //sample_rate; config.bits_per_sample = 16; config.i2s_format = I2S_STD_FORMAT; config.is_master = true; config.port_no = 0; config.pin_ws = 18; config.pin_bck = 5; config.pin_data = 19; config.pin_data_rx = 17; config.pin_mck = 0; config.use_apll = true;

i2s.begin(config);


Everything compiled fine, but I got the following panic when trying to run:

[I] TimeToText.h : 23 - say: 23:46 [D] SimpleTTSBase.h : 112 - digits: 0 [D] SimpleTTSBase.h : 113 - format: %0.0f [D] SimpleTTSBase.h : 117 - number: 14 Guru Meditation Error: Core 1 panic'ed (StoreProhibited). Exception was unhandled.

To stop the crashing, I made the following changes to TimeToText.h:

Line 111:
// addAll(ntt.say(time.minute,0u));
addAll(ntt.say((int64_t)time.minute));

Line: 123:
// addAll(ntt.say(time.minute,0u));
addAll(ntt.say((int64_t)time.minute));

Line 135:
// addAll(ntt.say(hour,0u));
addAll(ntt.say((int64_t)hour));

Line 150:
// addAll(ntt.say(hour,0u));
addAll(ntt.say((int64_t)hour));

After connecting the Talking Clock to a MAX98357A I2S amplifier, the "ticking" noise when the clock is meant to be silent became very apparent and annoying. It appears that the I2S driver continually sends its last buffer to the bus and, somehow, causes this tick.

Since my I2S device does not support a Mute pin, my workaround for this was the following:

// time at startup // <------------- i2s.begin(); ttt.say(timeInfo.time()); // <------------- i2s.end(); }

void loop() {
// speach output
if (timeInfo.update()){
i2s.begin(); // <-------------
ttt.say(timeInfo.time());
i2s.end(); // <-------------
// tts.say("SILENCE"); // ESP32: prevent noise at end
}
}


Hi,

I've tried several of your examples and they sound so much better than others I have come across. However, what I want to do is get tts to speak a number to three decimal places. I see the example where you convert the number to text (700234.2345 or whatever) but the number to speech example uses an integer. So far I haven't been able to get a non-integer version to work. Am I missing something?

I also have another issue when it comes to integrating your code with mine in a larger project but I need to send the errors I am getting for help with that.

Keep up the great work, though. You are way ahead of everyone else!

I had no problem adding a VolumeStream to the example streams-generator-i2s.ino sketch. However, I am having an issue attempting to add a VolumeStream to the Talking Clock example.

What I have done:

Added the following override to TextToSpeech.h:
TextToSpeech(SimpleTTSBase &tts, VolumeStream &sink, AudioDecoder &decoder,
AudioDictionaryBase &dict) {
tts.registerCallback(callback, this);
p_tts = &tts;
p_dictionary = &dict;
p_decoder = &decoder;
p_sink = &sink;
decodedStream = new audio_tools::EncodedAudioStream(&sink, &decoder);
begin();
}


In my main.cpp I have:

// MP3 DECODER
MP3DecoderHelix mp3;
AudioDictionary dictionary(ExampleAudioDictionaryValues);

// VOLUME STREAM
VolumeStream volumeTime;

// TIME TO TEXT
TimeToText ttt;
TextToSpeech tts(ttt, volumeTime, mp3, dictionary);

StreamCopy copierTime(i2s, volumeTime);


In my loop() I then have:

volumeTime.setVolume( 1.0 );
copierTime.copy();


Everything compiles, but when I run it, there is no audio from my I2S device. I am NOT a C++ expert, so I am probably missing something trivial. Any ideas?

Thanks!
