# Nuance Communications

Nuance Communications, Inc. was an American multinational software corporation based in Burlington, Massachusetts, specializing in speech recognition and artificial intelligence. It was acquired by Microsoft in March 2022 for $19.7 billion.

Nuance Communications, Inc. was an American multinational computer software technology corporation headquartered in Burlington, Massachusetts, known for its speech recognition and artificial intelligence software. The company's technology was widely used in healthcare, automotive, and customer service applications, and it became a prominent player in the commercial large-scale speech application market. In March 2022, Nuance was acquired by Microsoft in a deal valued at $19.7 billion, marking one of the largest acquisitions in Microsoft's history.

The origins of Nuance trace back to the Speech Technology and Research (STAR) Laboratory at SRI International, a leading research institute in audio processing and spoken language technologies. In 1994, the STAR Lab's work led to the spin-off of Corona Corporation, which was later renamed Nuance Communications. The company went public on the Nasdaq Stock Market in 1995 under the ticker symbol NUAN, focusing on commercializing advanced speech recognition systems.

## Early Speech Recognition Innovations

Nuance's foundational technology was developed at the STAR Lab, which had a long history of advancing speech and speaker analytics. In 1995, the SRI Language Modeling Toolkit (SRILM) was developed, providing tools to build and apply statistical language models for speech recognition, statistical tagging, segmentation, and machine translation. This toolkit became a cornerstone for many natural language processing applications.

In 1996, Nuance achieved a milestone by deploying the first natural language speech recognition system used by a major corporation. Charles Schwab & Co., Inc. adopted Nuance's technology to allow customers to obtain stock quotes over the telephone. The system was notable for its ability to recognize English words even when spoken by customers with various accents, demonstrating the robustness of the underlying algorithms.

The following year, in 1997, Nuance developed the first large-scale commercial dialog system for United Parcel Service (UPS). This system handled a high volume of package status inquiries, showcasing the scalability of Nuance's speech recognition platform for enterprise applications.

## ScanSoft and the Merger

The company that would eventually merge with Nuance began as Visioneer, Inc., incorporated in 1992 to develop scanner hardware and software, including the PaperMax sheetfed scanner and PaperPort document management software. In 1999, Visioneer acquired ScanSoft, Inc. (SSFT), a Xerox spin-off with roots in Kurzweil Computer Products, and the combined company adopted the ScanSoft name.

ScanSoft's history included the 1974 founding of Kurzweil Computer Products by Raymond Kurzweil, which developed the first omni-font optical character recognition system capable of recognizing text in any normal font. In 1980, Kurzweil sold the company to Xerox, where it became Xerox Imaging Systems (XIS) and later ScanSoft.

Prior to 2001, ScanSoft focused on desktop imaging software such as TextBridge, PaperPort, and OmniPage. The company shifted toward speech recognition with the December 2001 acquisition of Lernout & Hauspie assets, which had acquired Dragon Systems in June 2001. ScanSoft also acquired SpeechWorks in 2003, further expanding its speech technology portfolio.

In September 2005, ScanSoft acquired and merged with Nuance Communications, a natural language spinoff from SRI International. The resulting company adopted the Nuance name, combining two competitors in the commercial large-scale speech application business. The merger created a dominant player in the speech recognition market, with a broad range of products and services.

## Data Breach Incident

Between 2014 and 2017, Nuance experienced a data breach that exposed over 45,000 patient records. The incident raised concerns about data security in healthcare applications, where Nuance was a major provider of speech recognition and clinical documentation tools. The breach underscored the importance of robust security measures in handling sensitive medical information.

## Solutions and Product Evolution

Nuance's product portfolio evolved significantly over the years. In the early 2000s, the company expanded beyond desktop imaging to include speech recognition for telephony and mobile applications. By 2013, Nuance confirmed that its natural language processing algorithms supported Apple's Siri voice assistant, marking a significant partnership in the consumer technology space.

In 2019, Nuance spun off its automotive division as the independent company Cerence, allowing Nuance to focus more heavily on healthcare applications. This strategic move positioned Nuance as a leader in clinical documentation, medical transcription, and ambient intelligence for healthcare providers.

## Acquisition by Microsoft

On April 12, 2021, Microsoft announced its intention to acquire Nuance Communications for $19.7 billion, or $56 per share, representing a 22% premium over the previous closing price. The all-cash transaction was Microsoft's second-largest acquisition at the time, after its purchase of LinkedIn for $24 billion in 2016. Nuance's CEO, Mark Benjamin, remained with the company post-acquisition.

The deal faced regulatory scrutiny, with the UK's Competition and Markets Authority reviewing it for antitrust concerns. In December 2021, reports indicated that the European Union would approve the acquisition. The deal was completed on March 4, 2022, integrating Nuance into Microsoft's cloud and AI divisions, particularly enhancing Microsoft's healthcare offerings through [azure](https://www.wikiprompt.org/wiki/azure) and [artificial-intelligence](https://www.wikiprompt.org/wiki/artificial-intelligence) capabilities.

In May 2023, Nuance announced an unspecified number of layoffs, reflecting broader industry trends and integration efforts under Microsoft.

## Legacy and Impact

Nuance's technology has had a lasting impact on speech recognition and [artificial-intelligence](https://www.wikiprompt.org/wiki/artificial-intelligence) applications. Its early work in natural language processing and statistical modeling laid the groundwork for modern [machine-learning](https://www.wikiprompt.org/wiki/machine-learning) and [deep-learning](https://www.wikiprompt.org/wiki/deep-learning) approaches. The company's contributions to [neural-network](https://www.wikiprompt.org/wiki/neural-network) research and [large-language-model](https://www.wikiprompt.org/wiki/large-language-model) development, while not directly in the public domain, influenced subsequent innovations in the field.

Nuance's acquisition by Microsoft strengthened the latter's position in healthcare AI, with Nuance's Dragon Medical and other clinical solutions becoming part of Microsoft's [azure](https://www.wikiprompt.org/wiki/azure) ecosystem. The company's history, from its SRI roots to its merger with ScanSoft and eventual integration into Microsoft, illustrates the evolution of speech technology from research labs to mainstream enterprise applications.
