Incredible Human-Like AI Voices and Great Support for Client Automation **Rating:** 5.0/5.0 stars **Reviewed by:** Hasham G. | Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** April 03, 2026 **What do you like best about Synthesys?** I have been using Synthesys as part of my agency, where I essentially deploy it for clients. It allows us to help our clients automate and completely delegate important parts of their business to AI voice agents, such as appointment setting, automated follow-ups, handling inbound inquiry calls, and customer support. The technology is absolutely incredible, the voices sound almost exactly like Human voices, and most people assume it's a human on the other side of the phone. The customer support is great. We ran into a few problems setting it up, and support helped us out quickly. Overall, it's a very solid and well thought out platform. **What do you dislike about Synthesys?** The main thing I'd point out is that it still requires some level of understanding of AI to set up. To properly optimise the Agents, one needs to understand how to set up Knowledge bases, exit conditions, and integrations, etc. But it's still manageable. **What problems is Synthesys solving and how is that benefiting you?** Synthesys is solving the most fundamental, yet important, problem in modern businesses. Leads need to be contacted, qualified, booked in, and followed up with. Humans have done all of this, but now that Synthesys has solved this problem using AI, this allows us to operate without hiring several salespeople!. ### 2.
