Retired schoolteacher. Warm indirect register. Talks about family, food, and the weather first. Worries about whether you are eating enough.

Habla.
Own-voice evidence for every student. After a unit, each student retells it to a native-voiced character (a Mexican abuela, a bilingual Chicago college student), and you get their audio plus a transcript you can trust. Runs on our hardware, no student accounts. Optional: the base tier never depends on it.

How a Habla session works
Step 01
Pick a persona
Students choose from the cast based on scenario continuity, dialect target, or just curiosity. Every persona has a backstory, dialect, and visual.
Step 02
Talk in Spanish
Real conversation. Spoken or typed. Persona responds with their voice (ElevenLabs cloned) and their cultural register intact. No generic chatbot voice.
Step 03
Feedback after
Pronunciation scoring, register notes, sociopragmatic flags. The teacher sees the transcript. Students get one specific thing to work on.

02 / Under the hood
Built specifically for K-12 World Language. Not for adult app users.
Voice
ElevenLabs voice cloning calibrated per persona. A Mexican abuela does not sound like a Madrid teen. A Cuban-American college student does not sound like a Buenos Aires professor. Dialect is not a setting; it is the persona.
Visual
Live2D avatars with Wawa-Lipsync. Real-time mouth animation matched to phonemes. Not a static portrait, not an uncanny 3D head. Editorial illustration that moves with the voice.
Feedback
AS-units analysis for fluency, embedding classifiers for proficiency level, LanguageTool plus a fine-tuned model for grammar feedback. Specific, actionable, never drive-by corrective.
Privacy
Students join with a class code, first name only. No email collection from minors. Conversation transcripts live in the teacher dashboard, not in a vendor data lake. FERPA-safe by design.
