Voice Data and TTS Talent for a Telecom IVR Program in African Languages
A telecom provider needed native-speaker voice recordings in several African languages to build a text-to-speech voice for its automated phone support system, replacing a generic synthetic voice that customers found difficult to understand.

|---|---|
| Region | West and East Africa |
| Engagement type | Native-speaker voice talent recruitment and TTS training recording |
The challenge
The client's existing IVR system used a generic, poorly localized synthetic voice in several of its target languages, producing low comprehension and high call abandonment among customers in those markets.
The approach
Jwuma recruited and auditioned native-speaker voice talent in each target language, recorded structured prompt sets under studio-quality guidelines, and reviewed every recording for pronunciation accuracy and consistency before delivery to the client's TTS training pipeline.
Results
The client built a materially more natural-sounding, locally accurate IVR voice in its target languages, directly addressing the comprehension issues customers had reported with its previous synthetic voice.
Frequently asked questions
Why does IVR voice quality matter for telecom customer experience?
Because a poorly localized or hard-to-understand automated voice increases call abandonment and customer frustration, particularly in languages the original system did not support well.
How is voice talent selected and verified for a TTS program?
Through native-speaker auditions and recording review focused on pronunciation accuracy and consistency across the full prompt set.
Can this approach cover multiple African languages in one program?
Yes, provided verified native-speaker voice talent is recruited separately for each target language and recorded to a consistent studio standard.
