SoundHound AI, Inc. (Nasdaq: SOUN) is an American technology company specializing in speech recognition, voice synthesis, and music identification. Headquartered in Santa Clara, California, the company develops voice-enabled solutions for businesses, including drive-through restaurant ordering, automotive infotainment, and customer service automation. Originally founded as Melodis in 2005, it rebranded to SoundHound Inc. in 2010 and later to SoundHound AI in 2022, reflecting its expanded focus on Artificial intelligence and voice interfaces.
The company is best known for its music recognition app, SoundHound, which identifies songs by listening to short audio clips, and for Houndify, a platform that enables developers to integrate voice assistants into their products. Over time, SoundHound AI has pivoted toward enterprise voice AI, particularly in the restaurant and automotive sectors, processing over 100 million customer interactions by late 2024.
History
SoundHound AI was founded in 2005 as Melodis Corp by Keyvan Mohajer, Majid Emami, and James Hom. The initial focus was music recognition, competing directly with the Shazam app. In 2009, the company's music discovery app Midomi was rebranded as SoundHound, while a web version remained available at midomi.com until February 2025. The app's user base grew from 2 million in January 2010 to 100 million by September 2012, establishing SoundHound as a major player in mobile music identification.
In 2010, the company formally changed its name from Melodis Corp. to SoundHound. A significant milestone came in 2015 when Hyundai Motors began integrating the SoundHound music recognition app into the infotainment systems of select Hyundai and Kia models, marking the company's entry into the automotive sector. In December 2015, SoundHound launched Houndify, a voice interface platform designed to allow other products and services to incorporate voice recognition and natural language understanding.
The company continued expanding its voice AI capabilities. In April 2022, coinciding with its listing on the Nasdaq via a SPAC merger, it rebranded to SoundHound AI. In December 2023, SoundHound acquired SYNQ3 Restaurant Solutions, a provider of voice AI for restaurants, for $25 million. This acquisition accelerated its push into the restaurant industry, leading to partnerships with chains such as Jersey Mike's Subs and White Castle in 2023-2024. By October 2024, SoundHound claimed its phone ordering technology had processed over 100 million interactions with restaurant customers.
Further acquisitions followed: in June 2024, SoundHound acquired Allset, a restaurant ordering marketplace founded in Ukraine, and in August 2024, it acquired Amelia AI for $85 million, a company specializing in enterprise conversational AI. In September 2025, SoundHound completed its acquisition of Interactions LLC, another developer of AI for customer service markets.
Technology and Products
SoundHound's core technology spans speech recognition, natural language understanding, and voice synthesis. The company's proprietary Deep learning models enable fast and accurate voice interactions, often with real-time response capabilities. Houndify, launched in 2015, provides a suite of tools for developers to build voice-enabled applications, including custom wake words, speech-to-text, and text-to-speech services. The platform supports multiple languages and domains, making it adaptable for various industries.
The SoundHound app itself uses audio fingerprinting and Machine learning algorithms to identify songs, display lyrics, and provide song recommendations. The company has also developed voice AI solutions for drive-through restaurants, allowing customers to place orders via conversational voice interfaces. These systems integrate with point-of-sale (POS) software and are designed to handle complex orders with high accuracy.
In the automotive sector, SoundHound's voice assistants are embedded in infotainment systems, enabling drivers to control navigation, media, and communication hands-free. The company's technology is also used in smart speakers, mobile apps, and customer service call centers, where it automates routine inquiries and transactions.
Funding and Financial History
By June 2015, SoundHound had raised a total of $40 million across several funding rounds, with investments from Global Catalyst Partners, Translink Capital, Walden Venture Capital, and others. In January 2017, the company secured an additional $75 million in a round that included Nvidia, Samsung, Kleiner Perkins Caulfield & Byers, and other investors. This influx of capital helped fuel research and development in voice AI.
In January 2018, SoundHound's valuation reached $1 billion, marking its status as a unicorn. In May 2018, the company raised $100 million in a funding round led by Tencent, further solidifying its financial position. On April 28, 2022, SoundHound AI went public via a merger with Archimedes Tech SPAC Partners, at a valuation of $2.1 billion, listing on the Nasdaq under the ticker symbol SOUN.
However, the post-SPAC period brought challenges. In November 2022, the company implemented a 10% workforce reduction and salary adjustments, as reports indicated it had secured less than half of the anticipated funds from the SPAC merger. In January 2023, SoundHound reduced its workforce by approximately 50%. Despite these setbacks, the company secured $100 million in strategic financing in April 2023, providing a financial cushion for continued operations.
In February 2025, Nvidia disclosed in a regulatory filing that it had sold its stake in SoundHound, a notable development given Nvidia's earlier investment and the broader interest in AI companies.
Market Position and Competition
SoundHound AI operates in the competitive voice AI market, facing rivals such as OpenAI, Anthropic, and Google DeepMind, which offer large language models and conversational AI. However, SoundHound differentiates itself by focusing on vertical applications, particularly in restaurants and automotive, where its domain-specific models and integrations provide tailored solutions. The company's acquisition of SYNQ3 and Amelia AI strengthened its presence in customer service and restaurant ordering, areas where general-purpose AI assistants may lack specialized capabilities.
In music recognition, SoundHound competes with Shazam, which is owned by Apple. While Shazam has a larger user base, SoundHound has leveraged its technology to expand into broader voice AI applications, reducing its reliance on the consumer app market.
Awards and Recognition
SoundHound won the 2020 Webby Award for Productivity (Voice) in the category Apps, Mobile & Voice, recognizing its excellence in voice technology. The company has also been acknowledged for its innovations in speech recognition and natural language understanding, though specific details of other awards are not widely documented.
