Sahara CodeSwitch Africa Challenge 2026 – Win a Share of the $10,000 Prize Pool

Applications are open for the Sahara CodeSwitch Africa Challenge 2026, a technology competition inviting developers, researchers, startups, product teams, students, and other builders to create practical voice AI applications designed for Africa's multilingual environment.

The challenge focuses on code-switching, where speakers naturally move between languages during the same conversation. Participants will use Sahara's code-switching APIs to build real-world applications, test their performance, and compare their solutions against other speech models.

The total cash prize pool is USD 10,000, with additional opportunities for finalists to gain visibility, access partner networks, receive Sahara API credits, and explore potential pilot or deployment opportunities.

About the Sahara CodeSwitch Africa Challenge

The challenge is organized around the idea that voice AI should work effectively with the way people actually communicate across Africa. Many African speakers naturally combine English, French, or other languages with local languages in everyday conversations.

Participants are therefore challenged to build voice AI solutions that can understand code-switched speech and then perform a useful downstream task. Examples include voice assistants, spoken-language forms, health tools, customer-service applications, and other systems that can take action based on spoken input.

The competition is supported by Intron and partners including NVIDIA, CLEAR Global, Masakhane, Wema Bank, Branch, ARM, Gooey.AI, Co-creation Hub, PATH, and turn.io.

Challenge Categories

Participants can develop solutions in one of five broad areas:

Health

Solutions may address clinical documentation, patient intake, maternal health, public health, community health, hospital workflows, or frontline healthcare.

Legal and Public Services

This track covers applications such as court transcription, legal assistance, citizen services, civic reporting, complaints, justice access, and public-sector workflows.

Fintech, Telco and Customer Experience

Participants can develop voice banking, KYC, payments, collections, customer support, call-center, agent-assistance, or customer-insight solutions.

Agriculture and Education

Projects may focus on farmer advisory services, agricultural extension, tutoring, classroom learning, local-language education, or skills development.

Other High-Impact Use Cases

Other meaningful applications are welcome, including humanitarian response, accessibility, media, commerce, transportation, culture, and other areas where code-switching voice AI can create measurable value.

Prizes and Opportunities

The Sahara CodeSwitch Africa Challenge offers a total cash prize pool of USD 10,000.

In addition to the cash awards, top-performing teams may receive:

• Partner Demo Day access.
• Increased visibility among sponsors, judges, funders, and ecosystem partners.
• Potential pilot and deployment opportunities.
• Additional Sahara API credits.
• Recognition through Intron and partner channels.
• Opportunities to connect with potential collaborators and technology partners.

Eligibility Criteria

The challenge is open to:

• Developers and software engineers.
• AI and machine-learning researchers.
• Startups and product teams.
• University and student teams.
• Open-source builders.
• NGOs and civic-tech teams.
• Companies developing voice or customer-facing solutions.
• Individual builders interested in solving real-world African problems.

Applicants can participate individually or as part of a team. The organizers particularly encourage teams with expertise spanning development, research, product design, linguistics, healthcare, customer support, field operations, and other relevant disciplines.

Challenge Requirements

Each submission must meet several core requirements.

First, the solution must use voice to perform a downstream task. Simply converting speech into text is not sufficient.

Second, participants must benchmark their solution using code-switched audio across at least three speech models. This must include an Intron Sahara API as well as at least two other models selected by the participant.

Third, the project should target a specific vertical or real-world use case.

Where possible and permitted, participants should also provide code-switched audio samples used during testing together with basic information such as language pair, domain, accent or country, device type, and noise conditions.

How to Apply

To participate:

1. Register for the Sahara CodeSwitch Africa Challenge.
2. Apply as an individual or form a team.
3. Review the technical requirements and available Sahara API resources.
4. Select a meaningful problem or use case.
5. Build a voice AI application that performs a downstream task.
6. Benchmark the solution against at least three speech models, including Sahara.
7. Prepare the required demonstration, code, benchmark results, and supporting information.
8. Submit the completed solution before the deadline.

Participants can access the official challenge registration and resources through Intron's competition platform.
