Design the voice behavior
Define audience, persona, dialect, register, content types, pronunciation policy, and quality criteria.
TTS & STT
Text-to-speech development
Language design, pronunciation resources, voice evaluation, and product QA for natural synthesized speech.
The challenge
A technically clear synthetic voice can still mispronounce names, flatten phrasing, mishandle numbers, or adopt a persona that feels wrong for the market.
We define what the voice should sound like in context and turn language knowledge into pronunciation, text-normalization, prosody, and evaluation assets.
Evaluation covers isolated output and complete product interactions, including long-form, dynamic, and high-risk content.
How we work
Evidence first. Decisions visible. Knowledge transferred.
We adapt the depth and sequence to your product stage, language scope, and internal team.
Build language resources
Develop lexicons, normalization rules, phonetic guidance, exception handling, and evaluation sets.
Evaluate in product
Assess intelligibility, naturalness, prosody, pronunciation, consistency, and task fitness with native listeners.
Typical outputs

- Voice and language behavior specification
