Does TRULEO analyze tone, cadence, or other audio-only signals?

No, TRULEO only analyzes language within transcripts

While features like tone and cadence can be instructive in some situations, they are typically subjective metrics about how a person speaks. Many aspects of tone cannot be changed by a person, opening up tone analysis to bias. 

TRULEO uses a bias-free method of understanding interactions by focusing on language. Not everyone can choose their tone, but everyone has the opportunity to choose their words and get credit for professionalism in TRULEO.
