The industry leader in ASR accuracy, speed, and cost

Discover what Deepgram's Language AI solutions can do for you! Our speech-to-text APIs set the gold standard in the market in both performance and cost:

  • 36% more accurate than OpenAI Whisper

  • 5 times faster transcription speeds for pre-recorded audio and native streaming support that Whisper lacks

  • 25% more affordable than their managed API

Our flexible deployment options include on-premises, and private or public cloud where our GPU-optimized inference engine handles more concurrent audio streams and gives you faster results and lower total cost of ownership (TCO) than running Whisper yourself.

From transcription to understanding

Deepgram's Language AI models let you extract more value from your voice data without hiring additional experts across all your use cases.

  • Our Task/Domain-Specific Language Models perform downstream tasks like summarization and sentiment analysis faster and more affordably than Large Language Models (LLMs) can.

  • In the contact center domain, language understanding APIs boost user experience and agent productivity by capturing crucial conversational context, including the customer's purpose, agent's response, and follow-up actions.
