Sonos Voice Control: Custom French Voice with ReadSpeaker

Sonos, a global leader in sound experiences, sought to deliver a distinct, high-quality voice for its Sonos Voice Control system that would resonate with French-speaking users.

This personalized voice needed to handle complex, music-industry-specific content such as artist and track names, many of which required precise pronunciation and multi-language recognition.

Sonos needed an experienced voice partner to produce a branded voice that aligned with its identity, while overcoming the technical challenges of handling non-standard, industry-specific vocabulary.

ReadSpeaker’s VoiceLab team led the end-to-end development of Sonos’s French voice, using AI-driven deep neural network (DNN) technology.

The process involved extensive recording sessions with a carefully selected French voice talent, which VoiceLab used to train DNN models to ensure accurate pronunciation, even for words the talent hadn’t directly recorded.

The voice was optimized to handle artist names, track titles, and non-standard text content in multiple languages, providing a seamless, user-friendly experience.

The ReadSpeaker VoiceLab’s involvement spanned recording, data processing, model training, and quality assurance, ensuring Sonos received a voice that was consistent, natural, and expressive, fully embodying the brand’s identity in the French-speaking market.

With ReadSpeaker’s expertise, Sonos successfully launched a custom French voice for Sonos Voice Control, enhancing user engagement and reinforcing brand identity:

• Created a high-quality, branded French voice capable of handling complex music industry terms and multilingual content.
• Provided a seamless, natural voice experience that strengthens Sonos’s presence and identity in the French-speaking market.
• Delivered a robust, AI-powered voice solution that supports Sonos’s vision for innovative, hands-free user interactions.

“The collaboration with ReadSpeaker’s VoiceLab linguistic team has been essential… their approach to personalized voice is both innovative and extremely thorough.”
