Aug 17 (Reuters) - AI ‌startup Wispr Flow ​has ​nearly tripled its valuation to $2 billion in nine months, underscoring investor enthusiasm for voice tools that let users ‌work and write hands-free.

The AI dictation company said on Monday ⁠it has raised $280 million in a Series B round, led by existing investor ‌Menlo Ventures and including current ‌backers Notable Capital, NEA and Neo Ventures. New investors included Acrew, Forerunner, Goodwater and Peak XV.

The San Francisco-based Wispr had raised $25 ​million in a Series A extension round in November last year at a $700 million valuation. The total funding has now reached $361 ⁠million.

Global venture capital is flowing increasingly toward AI, robotics and chip startups, fueling a surge ​in billion-dollar companies, faster follow-on rounds and sharply higher valuations for a select group of high-growth firms.

Wispr Flow, ​whose software converts speech into text ‌for writing and workplace tasks, said its products are used at more than 10,000 enterprises.

"The value may ⁠be there if the growth rate survives, since triple digit quarterly growth off a small base is the easiest number in venture capital to generate ⁠for a few quarters and the hardest one to keep producing once the ​early adopters stop being the entire customer base," said Michael Ashley Schulman, partner at Cerity Partners.

The company on Monday also unveiled a preview of Canto, its ‌first proprietary speech-recognition model.

"We built this model for where people actually use Flow. In the hardest conditions, ‌with background noise, wind, heavy accents or music, error rates fall ⁠from more than 30% of ‌words to somewhere between ​5% and 10%," CEO Tanay Kothari said in a blog post.
