Comprehensive Voice AI Platform
Speech to Text
Power your products with world-class speech recognition. Everything developers need to build with confidence and ship faster. Unmatched performance guaranteed:
• Accuracy: 30% lower word error rate (WER)
• Speed: up to 40x faster inference time
• Cost: 3-7x lower price
Text to Speech
Generate lightning fast, human-like voices for real-time AI and high throughput applications.
• Quality: Human-like tone, rhythm, and emotion
• Speed: less than 250 ms latency
• Scale: Cost-efficient and optimized for high-throughput applications
Voice Agents
A unified voice-to-voice API that enables natural-sounding conversations between humans and machines. With one powerful API, create LLM-powered AI agents that listen, think, and speak with the same intelligence and emotive quality that a person can.
Don’t just take our word for it
Deepgram has been named a G2 Leader in 2025, solidifying its position in the industry and making it a top choice among developers. See why.
“As we’ve begun to roll out Deepgram to our customers, we’ve noticed the platform’s distinct ability to quickly and accurately transcribe product and company names.”
Adam Larsen
CTO, Creovai
“Deepgram’s ability to create custom voice-recognition models make the decision to bring the team on as a technology partner a no-brainer for us.”
“While Deepgram offers a technically excellent product, that’s not the only reason we ultimately chose them over their competitors. We liked working with their team. The team is extremely knowledgeable about the product and their customer service is unmatched. Other providers in the space offer nothing similar.”
Software Engineer
Podsights
“Most other speech-to-text vendors’ word error rates (WER) fell consistently between 75% and 80%, whereas Deepgram’s WER is consistently 90% to 92% for us.”
