# Wispr Flow raises $280M at a $2B valuation

By Steven Van · 2026-08-17

The Series B backs Canto, a new speech model Wispr Flow says cuts word error rates in noisy conditions from over 30% to 5-10%.

Wispr Flow raised a **$280 million** Series B led by existing investor Menlo Ventures, valuing the company at **$2 billion** and bringing its total funding to $361 million, [the company announced](<https://x.com/i/status/2089374511007424595>).

Alongside the round, [Wispr Flow](<https://creatorstoolbox.com/tools/wispr-flow>) previewed Canto, its first proprietary speech model, built for the noisy, real-world conditions people actually dictate in rather than quiet rooms. In the hardest cases, background noise, wind, heavy accents or music, word error rates drop from over 30% to between 5 and 10%. Across everyday use, Wispr Flow says the model should cut the number of dictations users need to edit by 30 to 35%.
