DeepL Unveils Voice API for Real-Time Transcription and Translation

On February 2, 2026, DeepL, a prominent international company specializing in artificial intelligence products and research, has officially launched its innovative DeepL Voice API. This groundbreaking product empowers developers by integrating real-time transcription and translation of spoken content into their applications, significantly boosting the multilingual capabilities of enterprises across various sectors.

Enhancing Multilingual Communication

The DeepL Voice API allows organizations to stream audio files and receive transcriptions in the source language, with options to translate into up to five target languages. This seamless experience ensures that language barriers do not hinder effective communication within businesses, paving the way for smoother interactions.

The API is particularly beneficial for companies that heavily rely on verbal communication, with call centers and business process outsourcing (BPO) service providers being among the first to adopt this solution. DeepL Voice aims to transform how multilingual assistance is managed, addressing staffing challenges faced by many call centers with an easy-to-use solution that integrates perfectly with existing systems.

Improving Operational Efficiency

By incorporating real-time transcription and translation into the workflow of customer service agents, the DeepL Voice API enables supervisors to address issues more effectively, allowing agents to assist customers in various languages without the need for transferring calls or relying on written communication for translations. This operational enhancement results in clear transcriptions and translations, facilitating quality checks and training for customer support teams.

Moreover, minimizing challenges linked to language barriers—such as prolonged calls, repeated contact, and costly misunderstandings—transforms the overall user experience for customers, potentially leading to increased satisfaction.

Gonçalo Gaiolas, product director at DeepL, emphasized, "When interacting with a customer service representative, the end user typically seeks to resolve a significant problem. However, they often face communication hurdles that lead to negative experiences. By equipping call center teams with tools for real-time communication in any language, we can transform what is often seen as a cost center into a revenue driver through exceptional customer service. This also simplifies the work for call center agents, reducing the need to transfer tasks to others or seek workarounds."

Expanding Recruitment and Talent Pool

The DeepL Voice API allows call centers to hire based on expertise rather than language proficiency, enabling them to recruit agents who understand the customer's issue and the business context, even if they do not speak the particular desired language. This shift not only broadens the talent pool but also helps control costs by decreasing the necessity for specialized language personnel.

In addition, real-time translation functionality ensures reliable coverage during urgent moments, such as overnight, weekends, or holidays when fewer specialized agents may be available. Agents can also enjoy bidirectional understanding, thanks to live audio translation alongside on-screen transcription and translation, allowing them to respond naturally and confidently in real-time.

Business Value and Operational Resilience

For industry leaders, the business benefits are manifold. Organizations can expand their language coverage without altering their hiring models, quickly cover new geographical areas, and support more client programs with the same core team. This control over customer experience, compliance, and costs becomes increasingly vital as operations scale.

The launch includes an early access program lasting six weeks for voice-to-voice features, beginning mid-February. This functionality allows agents to hear translated audio while communicating with clients in their preferred language, further enhancing the customer experience.

Availability

The DeepL Voice API will be accessible to all DeepL API Pro customers starting February 2, 2026. Companies interested in utilizing this groundbreaking technology can begin by exploring the DeepL API documentation or contacting the sales team for access.
