The other week’s success with the SYN6988 TTS chip was not repeated with three other modules I ordered, alas. Two of them I couldn’t get a peep out of, the other didn’t support English text-to-speech.
This one looks remarkably like the SYN6988:
Apart from the main chip, the only difference appears to be that the board’s silkscreen says YS-V6 V1.15 where the SYN6988’s said YS-V6E V1.02.
To be fair to YuTone (the manufacturer), they claim this only supports Chinese as an input language. If you feed it English, at best you’ll get it spelling out the letters. It does have quite a few amusing sounds, though, so at least you can make it beep and chime. My MicroPython library for the VoiceTX SYN6988 text to speech module can drive it as far as I understand it.
Here are the sounds:
|msga||Polyphonic Chord Beep|
|msgb||Polyphonic Chord Beep|
|msgc||Polyphonic Chord Beep|
|msgd||Polyphonic Chord Beep|
|msge||Polyphonic Chord Beep|
|msgf||Polyphonic Chord Beep|
|msgg||Polyphonic Chord Beep|
|msgh||Polyphonic Chord Beep|
|msgi||Polyphonic Chord Beep|
|msgj||Polyphonic Chord Beep|
|msgk||Polyphonic Chord Beep|
|msgl||Polyphonic Chord Beep|
|msgm||Polyphonic Chord Beep|
|msgn||Polyphonic Chord Beep|

Unknown “TTS Text-to-speech Broadcast Synthesis Module”
All I could get from this one was a power-on chime. The main chip has had its markings ground off, so I’ve no idea what it is.
Red and black wires seem to be standard 5 V power. Yellow seems to be serial in, white is not connected.
HLK-V40 Speech Synthesis Module
In theory, this little board has a lot going for it: wifi, bluetooth, commands sent by AT commands. In practice, I couldn’t get it to do a thing.
