Compared to accent training, the AI voice filter produces better results, faster. Enhancing the intelligibility of offshore agents in real-time, using a speech filter, results in a better overall customer experience. Lowering the abuse offshore agents encounter, due to their accents, improves the likelihood that agents will stay on the job. Improving the offshore customer experience makes it possible to offshore more, saving on costs. Plus it increases sales metrics.

AgentVoice
AgentVoice
AgentVoice is a platform for building AI‑powered voice agents that can make and answer phone calls and take meaningful actions, like booking meetings, sending texts, and updating CRMs, without requiring a developer. Each call flows through speech recognition to transcribe what’s said, a large language model to determine what to say and do, and an AI‑generated voice to respond naturally. Our agents don’t just respond, they execute tasks during or after the call using real data, memory, and tool access. You can create no‑code workflows that update CRMs, schedule meetings, send follow‑ups, screen leads, handle voicemails, or filter spam calls, all in the same call. Setup is fast, you can create and launch a working agent in less than 30 minutes, using no code: define your agent, choose a voice, connect your tools via 200+ native integrations, low‑code options, or a robust API and webhooks, then upload or generate a script.Starting Price: $50 per month -
