SpinVox, based in the United Kingdom, was a provider of voice-to-text conversion services. Founded in 2003 by Christina Domecq and Daniel Doulton, the company aimed to transform voicemail messages into readable text messages or emails. Initially, SpinVox worked in collaboration with telecom operators to offer its services to customers, converting voice messages into text using a mix of speech recognition technology and human transcriptionists.

The company grew rapidly and expanded its operations globally. SpinVox was headquartered in Marlow, Buckinghamshire, in the United Kingdom. It also had offices in London, San Francisco, and Marbella.

The main product of SpinVox was its voice-to-text conversion service. Customers could subscribe to the service through their telecom operators and have their voicemail messages automatically converted into readable text messages or emails. This service was offered in multiple languages and supported by a large team of linguists and technology experts.

SpinVox gained notable traction in the telecommunications industry, partnering with major telecom operators such as Vodafone, Alltel, and Skype. The company also formed joint ventures, collaborating with companies like American Tower Corporation and with VoxOx to expand its customer base. In terms of market position, SpinVox was a prominent player in the voice-to-text conversion market.

Its services were well-received globally, and the company experienced significant growth. However, SpinVox faced competition from other players in the industry, such as Nuance Communications. Despite its initial success, SpinVox faced controversy and legal disputes.

There were allegations of misleading customers regarding the involvement of human transcriptionists in the conversion process. These controversies affected the company's reputation and ultimately led to its acquisition by Nuance Communications in 2009. As of the latest information available, SpinVox no longer operates as an independent brand.

Its voice-to-text services have been integrated into Nuance Communications' offerings. Consequently, SpinVox's current status is that of an absorbed brand within Nuance Communications
