Your timing, kept
Text can’t always capture a pause, a laugh or a dramatic build. A performance can, and Echo keeps it.
Musa Echo
Keep the performance. Change the voice.
Musa Echo doesn’t read text. It listens. Record a line with your own timing and feeling, and Echo turns it into another voice while the words, pacing and emotion stay yours.
