Amazon’s Alexa Fund invests in three voice startups

Founded in 2015, Amazon's Alexa Fund is dedicated to helping start-up startup voice companies kickstart. This week, support was announced for a trio of new companies.

There is Bamboo Learning, which was one of the first partners of Alexa Presentation Language (APL) of Amazon. The beginning develops musical educational skills, teaching users about notes, instruments, chords and rhythm, along with other fragments of musical vocabulary.

Endel, meanwhile, is designed to use soundscapes to help users relax. According to the company, "our core algorithm is based on circadian rhythms, the pentatonic scale and sound masking. Sounds adapt to different inputs, such as time of day, weather, heart rate and location. "

There is also a health care startup, Aiva, that uses voice aids to help users get to the health care professions. Both Aiva and Endel are alumni of Techstars. The three companies will obtain funds from Amazon and will participate in Amazon's Demo Night.
