Welcome to Yuhalu Hmong text to speech for Romanized Popular Alphabet (RPA).


Hmong is a tonal language with classifiers, class nouns, adverbs, reciprocal verbs, phrasal verbs and others. Besides, Hmong words consists of monosyllable, disyallable and polysyllable.
When listening to songs, a person has to know Hmong well enough to understand because tones change, and these words or lyrics mean different things.

In Hmong RPA script, there are 6,076 syllables (exclude tone marker "d") for both blue Hmong and white Hmong dialects, and some excluded sounds such as prwv, toib, waw, wos, and wov.
In these 6,076 syllables, there is a pair out of the 420 pairs sounds the same for the 28 vowels ending with tone markers "g" and "s" and 30 aspirated consonants ending with "h", examples: "txhaig" sounds the same as "txhais"; "tshig" sounds as "tshis". So actually there are 5,656 sounds plus the other five, for a total of 5,661.
This software is written for this script, and it uses the syllable concatenation method. For simplicity, 6,081 sound files are recorded instead of 5,661, and the audio format is WAV, 44,100 hertz or samples per second in monaural.
In addition, there are some more sounds to read English alphabet from "a" to "z", from number "0" to "9", punctuations and other characters.
