The Sahara CodeSwitch Africa Challenge 2026 for African Developers & Startups ($10,000 Total Cash Prize Pool)

Reach us on

Applications are open for The Sahara CodeSwitch Africa Challenge 2026. The Sahara CodeSwitch Africa Challenge invites developers, startups, researchers, product teams, and builders across Africa to help solve one of the biggest unsolved problems in voice AI. Use Sahara’s new code-switching APIs. Build real applications. Benchmark what works. Help surface how well current speech models handle code-switched audio in real-world settings.

This challenge focuses on improving how speech technology understands African accents, local languages and code-switching, the common practice of switching between two or more languages within a conversation.

Sahara CodeSwitch Africa Challenge Prize Pool and Benefits

US$10,000 total cash prize pool
Top-performing teams will receive cash prizes across the competition categories.

Participants may also gain access to:

Partner Demo Day opportunities
Visibility with sponsors, judges, funders and ecosystem partners
Potential pilot and deployment opportunities
Additional Sahara API credits
Technical feedback and recognition.

The Challenge Task

Create or improve a real-world voice AI application

The transcript received can be used to perform a downstream task. Examples include a voice assistant that completes a booking, a voice-driven triage tool, a spoken-language form-filler, or a voice interface that takes an action on a user’s behalf.

Each submission must:

Use voice to achieve a downstream task (the agentic component), not simply convert speech to text.
Benchmark performance on code-switched audio input across at least three speech models, including an Intron Sahara API, and at least two other models of the team’s choice (global, local, open-source, commercial, pretrained or fine-tuned).
Target a specific vertical or use case (see categories below).
Where possible and permitted, submit code-switched audio samples used for testing, with basic metadata (language pair, domain, accent/country, device type, noise conditions).
