User:CebolaBros64/libNTTS Notes

The TTS used in all versions of Tomodachi Life (except the Japanese version) is made by Nuance.

apparently from some users who digged into tomodachi life's files, the text to speech they use is by Nuance, which does TTS stuff
however, at least from their demo
it doesnt sound at all like it, lol
even though the names match
MAYBE they use an extremely old version....

upon digging around in the files i found the folder thats responsible for the [TTS] engine.

a folder called libNTTS.
so far
inside the components_cmn_LZ.bin
are 2 files
lid.dat and synth_med_fxd_bet2f16.dat

from what i gather is that lid.dat is all the voice data and the synth_med_fxd_bet2f16.dat is the module that alternates pitch, speed and variation of the voice.

the dictionary_enu_LZ.bin holds a userdct_enu.dat that when opened in notepad++ are some words hence the name dictonary_enu
the header_LZ.bin is not a container file but is instead directly read, it seems to be the header code/config for the engine as well as something to do with "British English-Serena (TTS)"

Cool, I just figured out what exactly those .bin "ENU" files are, and how they can be swapped out for higher quality versions.

Tomodachi Life voices are created using low-quality versions of TTS voices from Nuance.

[...]Serena UK is the voice for the EUR version, and Samantha US is the US version's lol.

Hmm, I am almost certain almost any SAPI TTS voice would work,
I have been researching TTS voices and how they work, and it seems like almost every voice is the same file-format.

Yeah, they are the same voices, sorry for necro.

There's leftovers of a chinese TTS in libNTTS/header_LZ.bin, in all versions of the game that use libNTTS https://twitter.com/CebolaBros64/status/1213556841474613248
