Chatterbox from text
Chatterbox sees ordinary text only. It does not know that we want an isolated phoneme.
Chatterbox experiment Β· private
Which method says the phoneme correctly?
Play the three versions, then mark what you hear. Start with p, short a, schwa and th. If those fail, we do not convert the full library.
Your source recordings are not on this page.
Every play button below uses newly generated audio. βYour pronunciationβ means it guided the conversion locally; it is not the original clip. These are auditions, not privacy-approved release files.

What result lets us continue?
The exact-phoneme version must be accurate for the stop, vowel, schwa and digraph tests. The recording-guided version must be accurate and not recognisably you. A pitch change alone is not enough.
