Wispr Flow raises $280M at a $2B valuation
By Steven Van ·
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.
Alongside the round, 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%.
