Latvian text-to-speech has to honor a distinction most languages ignore in writing: vowel length, marked by the macron, where ā, ē, ī and ū are genuinely longer than their bare counterparts and can flip a word's meaning, so a synthetic voice that clips them sounds foreign or changes what was said. The language also carries three lexical pitch accents (level, falling and broken) on long syllables, a prosodic layer Latvian listeners hear even when it is not orthographically marked, which makes natural-sounding intonation harder than the relatively shallow spelling first suggests. Heavy nominal inflection means the same noun appears in seven cases with shifting endings, so a TTS engine must read stress on the first syllable consistently while pronouncing palatalized consonants ķ, ģ, ļ and ņ cleanly rather than collapsing them to plain stops. Realistic demand comes from Latvian e-government and library accessibility services, schools serving learners and the sizable Russian-speaking minority studying Latvian, and from media outlets producing audio versions of news for a small but tech-active market.
