TTS API speaking individual letters


Has anyone had luck getting the TTS API to correctly speak individual letters? For example using the input “P L A N T” results in randomly skipping some letters, or most of the time only speaking the first letter.

  • Tried a few different punctuation variations, and padding with words on both sides without success.
  • Tried with all 4 models, including, HD, 1106, 1106HD and different voices, same issue.

Hi and welcome to the Developer Forum!

You would be better off including the phonetic pronunciations of each letter, Double You, Eye, Sea, etc, etc. you could use traditional software to take a given input string and convert it to the spoken “word” versions.

I bet you can just put a period after each letter if you want it to say the letters.

If that doesn’t work, be be sure to actually ask ChatGPT how to do this!
