Finnish gaming and mobile apps

Audexum integrates as a single REST endpoint — no SDK required. Send your Finnish text, receive WAV audio. The free tier (10K chars/month) covers prototyping; paid plans start at €4/month for 100K characters.

Does Audexum handle Finnish vowel harmony?+
Yes. Finnish vowel harmony requires back vowels (a, o, u) and front vowels (ä, ö, y) to not co-occur in non-compound words. The synthesis model respects this constraint in prosody and does not mix harmony classes unnaturally.
How does Audexum handle Finnish geminate consonants?+
Finnish phonemically distinguishes single and double (geminate) consonants — e.g. 'tuli' (fire) vs 'tulli' (customs). Geminates are rendered with approximately twice the duration, as Finnish phonology requires.
Is Finnish on the free tier?+
Yes. Finnish is available on the 10,000 char/month free plan — no credit card required.
Which Finnish use cases is Audexum best suited for?+
Mobile app localization, accessibility layers (WCAG 2.2), language learning, and content narration are the primary use cases. For real-time Finnish TTS in voice assistants, the API latency is typically under 500ms for texts under 200 characters.
Audexum supports 33 languages.
Switch language with one parameter — same API endpoint, same pricing.
See the full 33-language list in the API docs or on the multilingual TTS guide.
