# Deepgram

Deepgram is a speech recognition and audio intelligence company that provides AI-powered transcription and voice AI APIs, founded in 2015 and headquartered in San Francisco.

Deepgram is a speech technology company that develops automatic speech recognition (ASR) and audio intelligence solutions. The company offers cloud-based APIs for speech-to-text transcription, voice AI, and audio analysis, targeting developers and enterprises. Deepgram was founded in 2015 by Scott Stephenson, a former Bridgewater Associates engineer, and is headquartered in San Francisco, California.

## History

Deepgram was founded in 2015 with the goal of applying deep learning to speech recognition. The company initially focused on building large-scale neural networks for audio processing. In 2018, Deepgram raised $12 million in Series A funding led by Nvidia, with participation from other investors. The funding was used to expand its research and development efforts. In 2020, the company launched its cloud-based speech recognition API, making its technology accessible to a broader audience. By 2021, Deepgram had raised an additional $47 million in Series B funding, led by Tiger Global Management, bringing its total funding to over $60 million.

## Technology

Deepgram's core technology is based on deep learning models, specifically [deep-learning](https://www.wikiprompt.org/wiki/deep-learning) and [neural-network](https://www.wikiprompt.org/wiki/neural-network) architectures. The company uses [transformer](https://www.wikiprompt.org/wiki/transformer) models and [sequence-to-sequence](https://www.wikiprompt.org/wiki/sequence-to-sequence) frameworks to process audio signals. Unlike traditional ASR systems that rely on phoneme-based models, Deepgram's approach uses end-to-end learning, which allows the system to directly map audio to text. This method is designed to handle diverse accents, background noise, and domain-specific vocabulary. Deepgram also offers features such as speaker diarization, sentiment analysis, and keyword spotting. The platform supports multiple languages and can be deployed via cloud or on-premises.

## Products and Services

Deepgram provides several products, including:

- **Speech-to-Text API**: Converts audio to text in real-time or batch mode.
- **Voice AI**: Enables voice assistants and interactive voice response systems.
- **Audio Intelligence**: Offers analysis of audio for sentiment, topics, and entities.
- **Nova**: A fast and accurate speech recognition model optimized for real-time applications.
- **Aurora**: A model designed for high-accuracy transcription in noisy environments.

These services are available through a REST API and SDKs for various programming languages. Deepgram's pricing is usage-based, with options for free tier and enterprise plans.

## Use Cases

Deepgram's technology is used in various industries, including call centers, healthcare, media, and finance. For example, call centers use Deepgram to transcribe and analyze customer interactions for quality assurance. Media companies use it for captioning and content indexing. In healthcare, it aids in clinical documentation. The company also serves developers building voice-enabled applications.

## Funding and Growth

Deepgram has raised significant funding from notable investors. As of 2023, the company has raised over $100 million in total funding. Its investors include Nvidia, Tiger Global Management, and other venture capital firms. The company has expanded its team and customer base, with clients such as [intuitive-surgical](https://www.wikiprompt.org/wiki/intuitive-surgical) and [tomtom](https://www.wikiprompt.org/wiki/tomtom) reportedly using its services.
