The missing step after text-to-speech
AI voices are great, but they pace themselves — you can't tell most TTS tools "make this exactly 15 seconds." Re-generating with different phrasing to hit a time is slow and hit-or-miss. Audio2Time is the post-step: drop in the generated audio, set the target, and it fits the take to the second by removing pauses first and then applying a gentle pitch-preserving tempo change. The voice still sounds like the model you picked.

Frequently asked questions
How do I make an AI voiceover fit an exact length?
Generate it in your TTS tool, upload to Audio2Time, set the target. Pauses are trimmed and a pitch-preserving tempo change lands it on the exact duration.
Why is my TTS voiceover always the wrong length?
TTS engines don't target a duration — they pace speech their own way, so you overshoot or undershoot the slot. A fit-to-length post-step solves it.
Will fitting it change how the AI voice sounds?
No — pitch is preserved and the change is small, so it sounds like the same take at the right length.
