What learners say
“I was a senior engineer for 4 years but never got promoted. My manager finally told me it was my communication in meetings, not my code. SpeakEvo's dialog practice was the only thing that actually fixed it.”

“I was a senior engineer for 4 years but could never get promoted. My manager told me it was my communication in meetings. SpeakEvo's salary negotiation and standup practice changed everything.”
Arjun S.
Lead Engineer, Bangalore
“The rephrasing coach and cultural notes completely changed how I write emails to US clients. I finally understand why "as per my last email" sounds aggressive in American English.”
Mei L.
DevOps Engineer, Singapore
“I used Duolingo for 2 years and could not survive a technical interview in English. Two weeks with SpeakEvo's system design dialog and I passed my first FAANG phone screen.”
Carlos R.
Full-Stack Developer, São Paulo
“The presentation simulator caught that I was saying "basically" and "you know" constantly. Fixing that alone made my sprint demos 10x more credible.”
Priya N.
Product Manager, Hyderabad
“Games make vocabulary actually stick. I learned more useful tech vocabulary in two weeks than in months of YouTube videos.”
Viktor K.
Backend Developer, Kyiv
“The Search & Learn feature is incredible. I typed "explain model performance to a non-technical CEO" and got an exact 3-step plan with the vocabulary and phrases I needed.”
