When voice is the primary use case and you want self-serve onboarding with transparent pricing. Edesy's native audio LLM architecture (Gemini Live, OpenAI Realtime) gives sub-500ms latency that pipeline-based platforms like Yellow.ai struggle to match. Most teams ship in under a week vs months on Yellow.ai.
Yellow.ai is a strong choice when you need true omnichannel — voice + chat + email + SMS + social — under one roof with a deep pre-built bot library and dedicated CSM. Their enterprise model fits large CX deployments where WhatsApp voice is one of many channels in a unified strategy.
Pipeline voice AI: speech → text (STT) → LLM → text → speech (TTS), with each step adding latency, errors, and lost emotional nuance. Native audio LLMs (Gemini Live 2.5, OpenAI Realtime) process audio end-to-end. Result: faster (sub-500ms), more natural turn-taking, better handling of partial speech and interruptions, and emotion detection. On a real WhatsApp call, the difference is immediately audible.
Both platforms support major CRMs (Salesforce, HubSpot, Zoho). Edesy uses real-time function calling — the AI hits your CRM API mid-call to fetch / update records. Yellow.ai has a deeper pre-built integration library if you have non-mainstream systems.
Yes — many customers do exactly this. Configure Edesy on a test phone number first, run side-by-side with Yellow.ai for 2-4 weeks, compare conversion / containment / latency metrics. Both work via Meta's WhatsApp Cloud API; you can have multiple BSPs configured.
Native audio LLMs, sub-500ms latency, self-serve in under an hour.
