SoundHound AI
Independent voice AI platform processing 100M+ monthly queries for automotive, restaurants, and IoT devices - publicly traded on Nasdaq (SOUN).
SoundHound AI is one of the largest independent voice AI companies, providing conversational intelligence APIs and finished voice products to automotive OEMs, restaurant chains, and consumer device manufacturers. Unlike Amazon Alexa or Google Assistant, SoundHound operates independently without ecosystem lock-in, which is a key differentiator for enterprises that want to avoid giving big tech companies access to their customer interaction data. The Houndify developer platform processes voice directly to intent using a speech-to-meaning engine that skips the intermediate text transcription step, reducing response latency. SoundHound became publicly traded in 2022 and counts Stellantis, Hyundai, LG, and Mastercard among its enterprise customers. The company acquired Amelia in 2024 to expand its AI agent capabilities for enterprise deployments.
