Where should I start?
If you want to add a voiceover to a video or presentation, start with the guide for the app you already use: each one walks you through writing a script, generating the voice in Speechma’s free text to speech, downloading the MP3 and importing it into that app. If your narration sounds stiff, read how to make AI voiceover sound human next; it improves results in every app.
Every guide uses the same basic workflow, so once you’ve done it once, the rest is quick. All the tools are free, need no account, and include commercial use of the audio you create.
