Final Cut Pro text to speech: an AI voiceover made on your Mac
Final Cut Pro records voiceovers from a microphone, but it does not turn text into speech. For narration, tutorials or character lines without recording, the practical way is to voice the script with a text to speech tool and import the audio.
The free SuperClonica engine does it on the same Mac, offline, with natural neural voices and character voices from the catalog. This guide shows the whole path from script to timeline.
Voice the script on your Mac
Install the engine once in Terminal with python3 -m pip install superclonica-cpu; the model downloads on the first run, then it works offline. Save the narration as a text file and voice it: superclonica --text-file narration.txt --voice M3 --lang en --normalize --output narration.wav. For a video with several scenes, voice each scene into its own file so that a rewrite means redoing only one. To pick a voice, try a line on voice pages in the catalog first; it is free and needs no account.
Import and place it
In Final Cut Pro, choose File, Import, Media, or drag the WAV files from Finder into the browser or straight onto the timeline. Connect each narration clip under the shots where it plays, then nudge it to match the picture. Lower the music under the voice with the clip’s volume or keyframes, and raise it again in the pauses.
Fix and polish
If a line sounds wrong, change the text and voice that file again instead of editing the waveform: it takes seconds. Commas and full stops add pauses, and numbers read most reliably when written as words; the guide to pauses and pronunciation has more tips. Every voice speaks 31 languages, so the same voice can narrate versions of the video in Spanish, German or Japanese.
