Decision framework: when to choose Resemble AI vs Tavus

Choose Resemble AI when:

• Your roadmap is audio‑first (voice assistants, IVR, in‑app narration, or audio ads)
• You need real‑time or batch voice generation, voice cloning, or speech‑to‑speech conversion
• Deepfake audio detection is a requirement

Choose Tavus when:

• You want real‑time, face‑to‑face AI interactions and/or generative video—at scale
• Engagement, trust, and comprehension benefit from a lifelike human presenter
• You want robust controls for behavior and outcomes (Objectives & Guardrails), plus fast, context‑rich responses (Knowledge Base, Memories, Raven‑0)
• You need an API‑first, white‑labeled platform with sub 1‑second conversational latency, 1080p video, and enterprise‑grade options (including SOC 2 and HIPAA on higher tiers)

Using both together

Many teams use Resemble AI for audio channels and Tavus for video touchpoints. This approach layers a humanlike presence where it matters most—voice for audio interfaces and AI humans for interactive, face‑to‑face video and video generation.

Summary

Resemble AI is focused on synthetic voice, with TTS, voice cloning, speech‑to‑speech, and a deepfake audio detection solution.
