Indonesian TTS datasets
An Indonesian voice that cannot say English loanwords sounds like a language learner, because those words sit in the middle of everyday sentences and not at the edges. The script includes them deliberately and the speaker is directed to pronounce them as Indonesian speakers do, which is not the same as the English pronunciation.
What TTS work in Indonesian requires
Speaker consistency across sessions
A voice recorded over several days drifts in pitch and pacing. If the target is one synthetic voice, either record in fewer, longer sessions or plan to re-record segments that fall outside tolerance.
Text the speaker can read fluently
A speaker reading unfamiliar script produces disfluencies that end up baked into the synthetic voice. Script selection matters as much as recording quality.
Phonetic coverage, not just volume
A long recording can still miss phonemes that are rare in running text. Coverage has to be checked against the language's inventory, not against word count.
The mistake that costs the most
The most common mistake is buying many hours from many speakers when the goal needed a few hours from one speaker, recorded properly.
The language-specific factor
In everyday speech, Indonesians mix in local languages (Javanese, Sundanese) and English loanwords heavily. Three language components inside a single sentence is normal, so word segmentation and annotation rules have to be fixed before collection begins.
