Solaria delivers unmatched accuracy, speed, and native-level transcription in 100 languages—including 42 underserved by any other STT model.
Gladia, an AI transcription and audio intelligence provider, announced the launch of Solaria, a next-gen automatic speech recognition (ASR) model designed to redefine real-time communications for call centers and other voice-first platforms. While outsourcing has long been a cost reduction strategy in the call center industry, businesses now face a new, critical challenge: providing seamless, multilingual support at scale. With 49% of global executives reporting financial losses due to language barriers1, the demand for scalable, high-quality multilingual solutions has never been greater. Solaria now empowers businesses to enhance and expand their customer service operations with AI-powered voice technology that delivers unmatched language coverage—supporting 40+ languages previously inaccessible with other solutions—without compromising quality or speed. Solaria: An Enterprise-Ready Model for Global Customer Experience The only speech-to-text (STT) engine built for true global scalability, Solaria was designed to meet the demands of today's contact centers, where both AI automation and human agents need high-accuracy, low-latency, and real-time multilingual support to succeed. The model achieves industry-leading results in speech recognition, delivering both unmatched accuracy and ultra-fast processing speed. Recent benchmarks show Solaria has reached an unmatched 94% Word Accuracy Rate (WAR) average in English, Spanish, French and other common languages, while maintaining an ultra-low latency of 270 ms, making the conversation feel natural and responsive. While real-time STT is often measured by speed alone, accuracy and language coverage are equally crucial for businesses providing seamless services across regions.Also Read: TransPerfect’s GlobalLink named leader in G2 Spring 2025 for Enterprise Translation Management
Unlike other STT models that prioritize speed over usability, Solaria balances industry-leading accuracy and speed with unmatched language coverage—100 languages in total, with exclusive support for 42 languages not matched by competitors. For high-population markets and key outsourcing hubs like Bangladesh, India, and The Philippines, native-level accuracy in regional languages is now offered through Solaria. With native-level transcription, real-time code-switching, and translation across all supported languages, businesses can expand into global markets without constraints.Designed for enterprise-scale voice automation, Solaria delivers:
- Best-in-class accuracy in high-population languages such as Tagalog, Bengali, Punjabi, Tamil, Urdu, Persian, and Marathi.
- Ability to adapt the model to industry-specific terminology (like medical or financial jargon) and have it extract critical data, like names, addresses, and numericals.
- Adaptive speech processing, ensuring high accuracy in noisy call center environments.
- Enterprise-grade data security, in full compliance with GDRP, HIPPA, and SOC 2.
