Speaking issues Coqui TTS Tacotron2 DDC model: Difference between revisions

Most models are trained with a dot, exclamation or question mark at the end. So always end a sentence to avoid model synthesizing weird output.

"ah" at end of sentence generally produces strange results. Short names produce a 12 second clip.

Examples:

If at the end of the input, adding punctuation to the end synthesizes correctly:

Example "Nelson Mandela" > "Nelson Mandela."

To speak acronyms as letters it needs to be formatted as:

"A. B. C. news"

Not:

"ABC news" "A.B.C. news"
