VoiceForm AI
Tamil AI Voice Assistant & Intelligent Form Filling
Speak Transcribe Auto-fill Submit
Presentation Agenda
A complete walkthrough of VoiceForm AI — from problem to pilot roadmap.
One Platform, Four Capabilities
VoiceForm AI unifies voice capture, form management, speech-to-form mapping, and operational intelligence in a single Tamil-first stack.
What It Does
Lets people fill forms by speaking instead of typing. Admins design forms, publish public URLs, and review submissions with full voice pipeline analytics.
Who It Serves
Schools, hospitals, government offices, HR teams, and field survey organizations that need hands-free Tamil data entry with admin oversight.
The Problem We Solve
Organizations lose time, accuracy, and completion rates when data entry depends on typing — especially in Tamil.
Slow Manual Data Entry
Long forms on mobile are painful to type. Field workers abandon forms before finishing.
Weak Tamil Support
Generic form tools lack Tamil speech recognition and culturally appropriate field parsing.
Opaque AI Costs
STT and LLM usage is billed per call with no per-form or per-request cost breakdown.
Fragmented Tooling
Separate products for forms, transcription, and analytics increase integration cost.
Industry Use Cases
Concrete scenarios where voice form filling saves time and improves accuracy.
Student Admission Form
Parent speaks student details in Tamil during school admission drive. No typing on mobile — review and submit in under 2 minutes.
Patient Intake Form
Nurse records patient symptoms and history by voice at reception. Auto-fills name, age, phone, and complaint fields for doctor review.
Citizen Service Request
Field officer captures citizen grievance details hands-free during door-to-door surveys. Works offline with Whisper, syncs when connected.
Employee Onboarding
HR speaks new hire details during orientation. Gemini AI extracts name, department, salary grade, and start date from natural speech.
Tamil Voice → Auto-Filled Form
Student admission form — speak once, fields populate automatically.
What We Built
A complete Tamil-first voice form platform — ready to demo and pilot today.
Voice Capture
Browser recording and file upload with automatic background transcription.
Form Builder
Drag-and-drop designer with 17 field types. Publish forms via public URL slug.
Public Voice Forms
Respondents speak or upload audio; fields auto-fill for review before submit.
Speech-to-Text
Local Whisper ASR or Google Cloud STT (Chirp 2) — per-request provider choice.
Smart Autofill
Rule-based NLP or Gemini 2.5 Flash AI — with automatic fallback to rules.
Admin Voice Reports
KPIs, daily cost rollups, pipeline history, audio replay, and CSV export.
Drag-and-Drop Form Builder
17 field types across 4 groups — design once, publish via public URL slug.
Admin Workflow
- Drag fields onto canvas in visual designer
- Set labels, validation, required flags, aliases
- Choose autofill mode: rules or Gemini AI
- Publish form — get shareable URL:
/forms/student-admission - Export responses as CSV from admin panel
- View audit log of all admin actions
Who Uses VoiceForm AI
Four personas — each with a dedicated entry point and workflow.
Field Agent / Citizen
Opens published form URL, speaks answers, reviews auto-filled fields, submits — no login required.
Knowledge Worker
Records voice notes, manages recordings, searches transcripts, favorites and archives notes.
Form Administrator
Builds forms in designer, manages users, exports responses, configures autofill and STT provider.
Operations Lead
Reviews Voice Reports KPIs, daily AI cost rollups, replays audio, audits pipeline history.
Business Benefits
Measurable value for field teams, administrators, and operations leads.
Faster Data Capture
Voice is quicker than typing — especially for Tamil and long narrative answers.
Higher Completion Rates
Auto-fill reduces friction; users only correct mismatches before submitting.
Cost Transparency
Estimated STT and Gemini USD per voice record — no surprise cloud bills during pilots.
Improvement Loop
Transcripts, corrections, and audio paths support tuning parsers and models over time.
Flexible Deployment
Local Whisper avoids cloud STT cost in dev; Google STT for production quality.
Single Integrated Stack
One codebase for forms, voice, and admin — lower integration overhead.
How It Works
From spoken Tamil to structured data in five simple steps.
Ideal for organizations that need hands-free, Tamil-first data entry
Enterprise Technology Stack
Modern, production-grade components — self-hosted and cloud-ready.
| Layer | Technology | Purpose |
|---|---|---|
| Frontend | React 19, TypeScript, Vite, MUI, Tailwind | Single-page app, form builder UI |
| Backend | FastAPI, Python 3.11+, SQLAlchemy 2 | REST API, async voice pipeline |
| Database | PostgreSQL 16 + pgvector | Structured data, future semantic search |
| Speech-to-Text | Whisper (local) + Google Chirp 2 | Tamil / English / Malayalam ASR |
| AI Autofill | Gemini 2.5 Flash + rule-based NLP | Map transcript text to form fields |
| Auth | JWT access + refresh, bcrypt, RBAC | Secure admin and user sessions |
System Architecture
Four integrated layers — from browser to database and AI services.
Presentation — React SPA
Form builder, public voice forms, admin panel, Voice Reports dashboard
Application — FastAPI Backend
Auth, forms CRUD, STT orchestration, NLP autofill, Gemini client, cost estimator
AI & Voice Services
Whisper microservice (port 8235), Google Cloud STT, Gemini 2.5 Flash autofill
Data — PostgreSQL 16
Users, forms, responses, voice dataset records, audit logs, Alembic migrations
Security & Governance
Enterprise controls built into Phase 1 — with Phase 2 hardening planned.
JWT Authentication
Access + refresh tokens, bcrypt password hashing, automatic token refresh in frontend.
Role-Based Access
