Wispr has raised $280 million in a Series B funding round that values the AI voice startup at $2 billion, giving the company fresh capital to expand beyond the dictation technology that built its early business.
Menlo Ventures led the round, which brings Wispr’s total funding to $361 million. Existing investors Notable Capital, NEA, Neo Ventures, 8VC and MVP Ventures participated again, while Acrew, Forerunner, Goodwater, Peak XV, Together Fund and Capital joined as new investors.
The financing follows Wispr’s funding announcement less than 10 months ago and comes as competition in AI-powered dictation intensifies. Wispr Flow competes with voice tools, including Willow, Monologue, Aqua, and Superwhisper, as well as lower-cost and free alternatives aimed at individual users.
Wispr expands beyond AI dictation
Wispr is using the new capital to broaden its product lineup, including its recently launched meeting note-taking tool. The product can capture meetings and produce summaries and action items, putting Wispr into a market that already includes services such as Granola, Fireflies and Read AI.
The expansion builds on Wispr’s push to make voice a broader computing interface rather than only a replacement for typing. The company has also expanded Flow to Android and increased its go-to-market presence in markets including India and the United Kingdom.
Wispr has experimented with hardware integrations as well, allowing users to dictate through compatible devices rather than relying solely on a phone or computer microphone.
New Canto model targets dictation accuracy.
Alongside the funding announcement, Wispr introduced Canto, its first proprietary speech model. The company says the model is designed to improve recognition in difficult real-world conditions, including background noise, wind, music and strong accents.
Wispr says word error rates in its most challenging tests fall from more than 30% to between 5% and 10% with Canto. Across typical use, the company expects the model to reduce the number of dictations requiring edits by 30% to 35%.
The improvement is particularly important for Wispr because accuracy is central to the appeal of dictation software. Users who repeatedly need to stop and correct their transcripts lose some of the speed advantage that comes from speaking rather than typing.
Wispr is also looking further beyond transcription. In July, the company launched its Advanced Interfaces Lab under Chief Scientist Ariya Rastrow, an early member of the Amazon Alexa team. The group is exploring new ways for people to interact with computers using AI, including systems that understand intent and context rather than merely converting speech into text.
With its latest financing, Wispr is positioning Flow as the starting point for a broader voice-based computing platform, while continuing to invest in the accuracy of the dictation product, which remains at the centre of its business.
