Importing AI Voice Lines into Unity, Unreal or Godot

To bring AI voice lines into Unity, Unreal or Godot, map each line in the download's Lines.csv to your game's dialogue ID, copy the WAV files into the project under names your dialogue system expects, and let the engine import them. Keep those names stable, and replacing a placeholder line with a final one is just copying a new file over the old.

What you get from abcVoiceover

A folder per script, with each line's kept take as a WAV file named by line number and speaker: 014 Blacksmith.wav.
Lines.csv: one row per line with Line, Voice, Text, Status and Audio file.
Takes are 24 kHz mono WAV, which every major engine imports.

See exporting your files for the full layout.

Map lines to your dialogue IDs

Your game refers to lines by its own IDs, like blacksmith_greet_02. Keep a spreadsheet with your IDs in the same order as the script in abcVoiceover, then add the CSV's Audio file column beside them. Now every ID has its file, and a short script can copy and rename the files:

ID,                     Audio file
blacksmith_greet_01,    013 Blacksmith.wav
blacksmith_greet_02,    014 Blacksmith.wav
blacksmith_farewell_01, 015 Blacksmith.wav

Filter on the Status column first: for a release build you probably want only Saved lines.

Name files for the engine, not for abcVoiceover

The download's names follow the script's line numbers, which change if you insert or move lines. Your game's names shouldn't. Rename on the way in (blacksmith_greet_02.wav), and the engine's references never depend on script order. Swapping a placeholder for a final take is then just copying a new file over the old one with the same name; the engine re-imports it and every reference keeps working.

Unity

Copy the WAVs into a folder under Assets; each becomes an AudioClip.
In the import settings, short lines and barks suit Decompress On Load; long narration suits Streaming. Vorbis compression keeps builds small.
Mono is right for dialogue, especially if it plays positioned in 3D.
Reference clips from your dialogue data by the stable names, or through Addressables.

Unreal Engine

Drag the WAVs into the Content Browser; each becomes a Sound Wave.
For subtitles and speaker data, Unreal's Dialogue Wave and Dialogue Voice assets link audio to text and speaker.
Unreal can import a CSV as a Data Table, so a table of dialogue IDs, text and file names can come straight from your spreadsheet.

Godot

Copy the WAVs into the project; Godot imports each as an audio stream.
Check the Import dock: dialogue shouldn't loop.
Load lines by path from your dialogue data, or with a dialogue addon that maps IDs to audio.

Audio middleware

FMOD and Wwise both import WAV files. Import the renamed files into your dialogue events, or Wwise's dialogue workflows, the same way as recorded VO. Keeping the same file names is what lets placeholder and final audio swap cleanly.

Subtitles

The Text column is each line's text, so it can feed your subtitle table. If you respelled names to get them pronounced right, keep the proper spelling in the subtitle data.
