Helloduty

Helloduty is building a Voice AI platform that delivers educational content through phone calls—empowering marginalized communities with access to vital health, financial, and agricultural knowledge. Designed for low-tech environments and trained on African voices and accents, the system allows users to ask questions via phone calls and receive AI-generated responses in their local language, without needing smartphones or internet access.

Millions across Africa remain disconnected from the digital economy due to:

Low smartphone and internet penetration

Language barriers with mainstream digital assistants

Lack of culturally-contextual guidance

NGOs and social programs struggling to scale outreach

This leaves marginalized groups excluded from life-changing health, financial, and agricultural knowledge.

Helloduty’s platform integrates:

Whisper Large: Transcribes African-accented speech from phone calls

Tacotron 2 + WaveGlow: Converts responses into clear, natural African voice outputs

Vector Database + Retrieval: Contextually queries domain-specific content

Multilingual Voice Support: Enables two-way communication in local languages

This enables NGOs and social organizations to deploy pre-trained voice assistants that work via simple calls, 24/7.

Democratizes access to knowledge for digitally underserved populations

Supports NGOs in scaling educational outreach to remote regions

Enables trusted, low-cost, voice-based engagement

Empowers users in their own language and dialect

Helloduty operates on a B2B2C model:

NGO & nonprofit subscriptions for voice assistant deployments

Custom voice training for thematic domains (e.g. maternal health, smallholder finance)

Pay-per-call or usage-based models for large-scale partners

Working prototype deployed via phone call

Models trained and integrated with demo datasets

Early NGO interest and pilot commitments

Grant-funded to date

Helloduty is seeking:

GPU compute (A100 or V100) to improve training & inference speed

NVMe SSD storage to support fast response and voice synthesis

Partner NGOs for scale-up in priority sectors (Health, Finance, Agri)

Exposure to regional telcos for improved call routing and integration

Support inclusive access to Voice AI that works without internet and speaks your language.
