- "Give this Mii a voice! You can select a preset or random setting or customize it yourself."
- — Tutorial, Tomodachi Life
Voice is an adjustable setting that determines a Miis manner of speech. There are 6 preset voices: male child, female child, male adult, female adult, male elder, and female elder. Voice can also be randomized and customized using the 6 different settings: Pitch, Speed, Quality, Tone, Accent and Intonation.
This should give you all you need to know about Mii Voices
Pitch: How high pitched your voice overall sounds on your Mii.
Speed: How fast your Mii talks.
Quality: How understandable your Mii is. A lower quality means a very low voice
Tone: How high sounded your Mii sounds.
Accent: Normally doesn't do much, but little changes. All the way to the right helps with making Robot Miis.
Intonation: How you normally sound during a sentence. 1 is normally. 2 ends higher, like with a good attitude. 3 is a explaining-like voice. Going high to low. 4 is normally the same throughout the whole sentence.
