AI is helping users automate many tasks that were done manually. One of these processes is speech-to-text and text-to-speech using generative AI models. This article will explore the Deepgram service's capabilities and applications. It has made great strides in this field.

What is Deepgram?

Deepgram is a platform offering speech recognition and text processing tools for creating transcriptions and voiceovers using deep learning algorithms. The San Francisco-based company of the same name developed it and has been running the project since 2015. Its advanced text-to-speech and speech-to-text technologies provide users with accurate, fast, and scalable transcription and speech generation services for various industries and applications.

Deepgram transcribes audio recordings in real-time and returns the generated text via an API request. It can also perform these actions in reverse order. The system’s algorithms support 30+ languages and 40+ file types, transcribing hour-long recordings in 8 seconds. Additionally, it summarizes, analyzes sentiment, and identifies content topics.

Deepgram offers a diverse and comprehensive range of pricing plans for the platform’s various services. The main ones are three package plans. They provide full access to speech-to-text, text-to-speech, and audio intelligence AI models and endpoints. These include:

  • Pay As You Go ($200 in free credits, top up as needed, up to 100 concurrent speech-to-text requests, 5 Deepgram Whisper Cloud requests, 40 API WebSocket connections, 2 batch API requests, and 10 Deepgram Audio Intelligence requests).
  • Growth (Prepaid $4-10k annually; credits are used as resources are consumed, up to 100 concurrent speech-to-text requests, 5 Deepgram Whisper Cloud requests, 80 API WebSocket connections, 3 batch API requests, and 10 Deepgram Audio Intelligence requests).
  • Enterprise (For companies with large data volumes and/or extended deployment/support requirements, pricing is upon request).

Throughout its operations, Deepgram has raised over $100 million in venture capital funding. The largest round of $72 million occurred in 2022 as part of Series B, setting a record for AI speech developers.

How Deepgram's Technology Works

The platform's architecture enables a fast and efficient process for converting speech to text and vice versa. This process has several stages. First, the original audio is digitized. Then, it is split into small chunks for analysis. Then, AI models in the platform automatically process these segments. They extract features and patterns.

The extracted elements are then passed to deep learning algorithms, which generate a text transcription based on the data. The final text is processed (sentiment analysis, summarization). It is then sent to the client app via API.

At the core of the service is the Deepgram Engine, which uses specially trained neural networks and deep learning models. Another key component is the Deepgram API. It supports automated, large-scale data transfers. It also integrates with external systems and apps.

As of 2024, the platform offers the following tools:

  • Deepgram Voice AI Agent. A universal voice-to-voice API interface designed for developing AI voice agents that can listen, speak, and analyze speech in real time. Instant responses and natural voice generation allow them to engage in smooth conversations on various topics.
  • Deepgram Text to Speech. The Aura deep learning model generates natural human speech from text with a latency of less than 250 ms. It automatically selects the appropriate tone, rhythm, and emotions, making it ideal for voice bots and conversational AI applications.
  • Deepgram Speech to Text. The next-generation Nova neural network converts audio into text with a latency of less than 300 ms and is 22% more accurate than existing solutions, recognizing over 30 languages and dialects. The Whisper API interface supports built-in diarization, word-level timestamps, and larger file uploads.
  • Deepgram Audio Intelligence. The language models here automatically perform various operations with speech data, including summarization, sentiment analysis, topic identification, and intent recognition. They adapt to specific topics and tasks, providing high-quality, fast insights.
