Speech Synthesis shield DFR0273 - Arduino hangs after the first sentence pronounced

Hello,
I have a big trouble with my Speech Synthesis shield on an Arduino Mega2560. I have checked the power source is powerful enough and memory available for the sketch is huge.

Here my speech definitions :
Code: Select all
byte voiceJarvisArmor = 0; char volumeLevel5[] = "5\0"; char answerJarvis_defaultMode[] = "the armor is switched to default mode\0"; char answerJarvis_initCompleted[] = "the systems are initialized. the armor is fully functional\0";

Here my speech function:
Code: Select all
void ttsJarvisSays (byte voiceType, char ttsJarvisSentence[]) { byte ttsJarvisBuffer[500]; SpeechSynthesis.buf_init(ttsJarvisBuffer); SpeechSynthesis.English(ttsJarvisBuffer,4,volumeLevel5); SpeechSynthesis.English(ttsJarvisBuffer,6,ttsJarvisSentence); SpeechSynthesis.Espeaking(0,voiceType,4,ttsJarvisBuffer); while(Serial.read()!=0x41) {} while(Serial.read()!=0x4F) {} }

here the main loop and setup :
Code: Select all
void setup(){ Serial.begin(9600); } void loop() { ttsJarvisSays (voiceJarvisArmor,answerJarvis_initCompleted); ttsJarvisSays (voiceJarvisArmor,answerJarvis_defaultMode); }

The first sentence is properly pronounced, but nothing after "ttsJarvisSays (voiceJarvisArmor,answerJarvis_initCompleted);" is executed. The Arduino seems to be hanged.

What is wrong ? Any idea ?

Best regards

Can you try commenting both
while(Serial.read()!=0x41)//waiting synthesis complete
{}
and
while(Serial.read()!=0x4F)//waiting play complete
{}
And then check the result. I checked libs that it seems that there is no 0x41 and 0x4f would be written in serial, which means it will be stuck in the while loop forever. xuegangxiao117

2019-08-13 03:21:27 Hi, I have the same problem:

this works (in setup)

Code: Select all

 SpeechSynthesis.buf_init(ssr);//Clear the buffer
   SpeechSynthesis.English(ssr,4,"5");//volume in grade 5
   SpeechSynthesis.English(ssr,6,"Booting up");//"6" means synthesis in English; "cooki"is the content
   SpeechSynthesis.Espeaking(0,16,4,ssr);//Executive commands above, "0" is synthesis command; "19" select speaker; "4" speech function
   while(Serial.read()!=0x41)//waiting synthesis complete
    {}
   while(Serial.read()!=0x4F)//waiting play complete
    {}
   SpeechSynthesis.English(ssr,4,"9");//volume in grade 9

and this doesn't send the execute command (led remains on, and shield 'busy' led remains off)

Code: Select all

 SpeechSynthesis.buf_init(ssr);//Clear the buffer
    SpeechSynthesis.English(ssr,4,"9");//volume in grade 9
    SpeechSynthesis.English(ssr,6,"Okay");//"6" means synthesis in English; "cooki"is the content
    SpeechSynthesis.Espeaking(0,19,4,ssr);//Executive commands above, "0" is synthesis command; "19" select speaker; "4" speech function
    
    digitalWrite(LED, HIGH);
    while(Serial.read()!=0x41)//waiting synthesis complete
    {}
    digitalWrite(LED, LOW);
    while(Serial.read()!=0x4F)//waiting play complete
    {}

Found any solution? infoatphp
