DeepL has launched the general availability of its DeepL Voice API, enabling developers to integrate real-time voice transcription and translation directly into applications. The API supports streaming audio input for instant transcription in the source language and simultaneous translation into up to five target languages, delivering a seamless multilingual experience that removes communication barriers in spoken interactions.

Contact centers and BPOs frequently struggle with language coverage, leading to longer handling times, repeated contacts, escalations, and higher operational costs. The DeepL Voice API addresses these pain points by embedding real-time transcription and translation into existing workflows. Supervisors gain better visibility and coaching opportunities through accurate transcripts, while agents can respond naturally and confidently without relying on workarounds or language-specific transfers.
"When interacting with a customer service representative, the end user is often trying to resolve an important issue, so facing communication barriers often leads to a negative experience," said Gonçalo Gaiolas, Chief Product Officer at DeepL. "By equipping contact center teams with tools that enable real-time communication in any language, we can turn what is often perceived as a cost center for a business, into a revenue generating one through customer excellence. This also makes the work of contact center agents smoother, reducing the need to pass tasks to others or seek workaround solutions."
Businesses can now expand geographic coverage, onboard new markets faster, and support diverse client programs without overhauling hiring or infrastructure. The API supports reliable performance during peak or off-hours when specialized agents may be unavailable, while maintaining compliance and quality standards through consistent, auditable transcripts.
The early access phase for voice-to-voice functionality will further enhance the experience by delivering translated audio output, enabling fluid, natural conversations across languages.
DeepL API Pro customers can begin integrating the Voice API immediately via the official documentation, with sales support available for onboarding and custom needs.
