Common questions
Which languages does VALSEA support?
VALSEA supports 181 languages, dialects, and accents, with particular strength in multilingual and accented speech across Asia. Code-switching — switching languages mid-sentence — is handled as part of the same conversation.
Is Translator different from the API?
Translator is the fastest way to try the VALSEA speech engine with no setup. The API gives you the same underlying capability to embed into your own app, call flow, agent, meeting workflow, CRM, or internal system.
How is VALSEA different from a generic translator?
Generic translation tools focus on text or sentence-by-sentence translation. VALSEA is designed around spoken conversations: accents, mixed languages, transcription, translation, semantic understanding, and structured outputs for downstream workflows.
Can I start small with the API?
Yes. API usage starts from $5, so you can test VALSEA on real audio before scaling a production workflow.
Does Translator require an integration?
No. Translator runs directly in the browser. Open it, speak naturally, and use it as the quickest way to experience VALSEA before deciding what you want to build.
