Where can I get audio suitable for animating dialogue?

I can’t provide copyrighted audio from live-action movies or TV series. Using that audio without permission can infringe copyrights.

Alternatives you can use for animating dialogue:

• Public domain films and recordings. Many early films and radio dramas are public domain and free to use.
• Creative Commons–licensed audio (look for CC0 or CC BY licenses that allow reuse). Sites: FreeSound, Internet Archive, Wikimedia Commons.
• Stock dialogue or voice clips from royalty-free libraries (e.g., Pond5, Storyblocks) — check license terms for reuse in your project.
• Text-to-speech (TTS) with expressive voices. Modern TTS can produce natural-sounding dialogue and you can edit timing easily.
• Hire voice actors (freelance marketplaces like Fiverr, Voices.com) to record custom lines tailored to your animation.
• Record your own actors or friends — gives full control and clear rights.
• Use dialogue extraction tools on audio you legally own to isolate speech (only if you have the rights to use that source).

If you tell me the style/era/character types and whether you need free or paid options, I can suggest specific sources, keywords to search, or sample TTS settings to achieve the sound you want.
