Deepgram Nova-3 was recognized for setting a new standard for transcription accuracy, customization, and real-time multilingual capabilities. In particular, TMC highlighted breakthrough performance in noisy, real-world conditions (i.e., call centers, drive-thrus, and emergency response). This is thanks to innovations in acoustic modeling, audio-text alignment, and domain-specific vocabulary handling. As the first model to offer real-time transcription across multiple languages and self-serve customization via keyterm prompting (without retraining), Nova-3 makes enterprise-grade speech recognition more flexible and accessible than ever.
Nova-3 also boasts an industry-leading batch word error rate (WER) of 5.26%, extending its lead over the next-best competitor by 47.4% (10% WER). This reduced error rate translates to more accurate transcriptions for industries that require high precision, such as healthcare, legal, and finance. In streaming WER, Nova-3 leads with a WER of 6.84%, extending its advantage over the next-best competitor by 54.2% (14.92% WER). This improved accuracy ensures real-time, reliable transcription for applications like call centers and virtual assistants, thereby enhancing the overall customer experience.
Whether handling complex accents, mixed-language conversations, or sensitive data redaction, Nova-3 enables smarter, faster, and more accurate voice-powered applications across industries.
“It gives me great pleasure to recognize Deepgram as a 2025 Voice AI Technology Excellence Award recipient,” said Rich Tehrani, CEO of TMC. “Our judges were thoroughly impressed not only by the strength and features of the product, but by Deepgram’s commitment to delivering world-class customer experiences.”
“We’re honored to receive a 2025 CUSTOMER magazine Voice AI Technology Excellence Award. It’s a powerful validation of the work our team has done to push the boundaries of what voice AI can deliver,” said Scott Stephenson, CEO and Co-Founder, Deepgram. “The market is facing enormous pressure to deliver faster, more accurate, and more adaptive voice solutions in environments that are noisier, more complex, and more multilingual than ever before. Nova-3 rises to that challenge by combining unmatched accuracy, real-time multilingual transcription, and instant self-serve customization, which are capabilities no other provider can deliver together at scale.”
