Sahara v2.5 expands bilingual speech intelligence with 12 models built for conversations that naturally move between languages.
Sahara v2.5 can follow one conversation as it moves naturally across English, Kinyarwanda and French without resetting context.
Sahara v2.5 extends from understanding African speech to generating natural voice responses across 13 supported languages.
Seven additional languages expand Sahara v2.5 from 56 to 63 total languages, bringing African voice AI to more speakers, markets and real-world use cases.
Sahara v2.5 improves recognition quality for real-world African speech, helping voice systems understand conversations more reliably across practical environments.
From collections and healthcare to courtrooms and clinical documentation, Sahara is already delivering measurable outcomes across real African workflows.
BRANCH
Sahara-powered Branch collections agents recovered more than ₦1.2 million in delinquent loans in one week, with record after-hours and weekend repayments, outperforming human agents on delinquent loans over 356 days.
BRANCH
Collaborating with Intron to build a Branch-aligned collections bot was a rewarding experience. Customers engaged naturally even after hours and on weekends. Conversations were human and effective at delivering real payments on delinquent loans, sometimes over 2 years old. Adding local language and language-mixing support in this v2.5 release helps us reach even more customers.
AUDERE
Youths across South Africa can now speak naturally with Audere’s Self-Cav reproductive health WhatsApp chatbot using voice to express themselves freely instead of being confined to text chat.
ARM
Using Intron AI models, we’ve seen significant improvement in transcription and summaries compared to models we previously explored. Their systems capture context and nuance better, leading to more accurate results.
OGUN STATEOver one year working with Intron, deployment has grown from an initial 3 pilot courts to 9 courts, with the goal of bringing all 18 courts across the state on board. Yoruba is frequently spoken during testimony, and Sahara v2.5 helps ensure those segments are properly captured in court records.
NAIROBIA 14-minute Swahili-English doctor-patient consultation in Nairobi is converted into a structured clinical note in less than 30 seconds, reducing documentation burden so physicians can focus more on patient care.
PAMOInternet connectivity had blocked the adoption of many transformative solutions. Intron’s offline medical scribe deployment has transformed clinical operations. At over 2,000 consultations using voice AI and a 4× documentation speed improvement, the team is now benefiting from AI without depending on reliable internet.
GOOEY.AI
On 4 of 6 Nigerian languages, independent Medical Question Answering benchmarks for the Gates Foundation and CLEAR Global showed Intron to be on par with or better than transcription alternatives including Gemini and Meta’s Omnilingual LLM. Sahara v2.5 is one of the first dedicated models for African code-switching they have evaluated.

Recover more without adding more agents.
Intron voice agents reach borrowers consistently with localised, human-like repayment conversations. Automate reminders, promise-to-pay capture, rescheduling, escalation, and after-hours calling across English, Pidgin, Hausa, Yoruba, Igbo, Swahili, and more, including customers who switch between two of them in the same call.
Reduce wait time. Resolve routine issues automatically.
Move from rigid IVR to intelligent voice self-service. Customers check balances, report failed transfers, block cards, request statements, ask repayment questions, and get app support. Complex cases escalate to your agents with the transcript, summary, and customer intent already attached.
Turn customer conversations into revenue.
Voice agents qualify leads, explain products, follow up on abandoned applications, reactivate dormant customers, and route high-intent prospects to your team. Call summaries, sentiment, intent, and next-best actions flow back into your CRM.
Make onboarding easier for every customer.
Customers complete KYC, merchant forms, loan applications, and account opening by speaking instead of typing. Intron captures names, addresses, dates, IDs, income details, repayment preferences, and business information accurately, with structured outputs your downstream systems can use.
Analyse every call. Coach every agent. Catch risk earlier.
Every customer conversation becomes structured intelligence. Intron transcribes, summarises, scores, and analyses calls for compliance gaps, weak verification, fraud risk, churn signals, customer sentiment, and agent performance.
Let customers bank by speaking naturally.
