Our take
Pick Kokoro TTS if you're a developer who want a small local voice with readable phonemes. Pick Piper if you're self-hosters who want a file or a speaker on-device. Skip Kokoro TTS if you're producers who need a cloned actor VO (ElevenLabs). Skip Piper if you're people who want a cloned cinematic VO (ElevenLabs) or a phone agent (Vapi).
