General[edit | edit source]
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.

Input string formatting[edit | edit source]
Phrases ending in "ah"[edit | edit source]
"ah" at end of sentence generally produces strange results. Short names produce a 12 second clip.
Examples:
- Nelson Mandela
- pergola
Mitigation[edit | edit source]
If at the end of the input, adding punctuation to the end synthesizes correctly:
Example "Nelson Mandela" > "Nelson Mandela."
Acronyms[edit | edit source]
To speak acronyms as letters it needs to be formatted as:
"A. B. C. news"
Not:
"ABC news" "A.B.C. news"
