What is Synthflow AI?

Synthflow AI is an end-to-end voice agent platform for enterprises, using customizable low-latency AI agents to automatically handle incoming and outgoing phone calls. It comes with a communication network, a test sandbox, and monitoring and analytics tools, creating a reusable workflow for voice automation from setup to launch. For enterprises looking to expand their sales and customer service call capacity, it can deliver measurable returns within weeks, ensuring that every incoming call is answered promptly.

Who is it for?

Enterprises needing to scale up phone call capacity: Sales and customer service teams that want to answer more incoming calls and seize more opportunities without hiring additional staff.
Companies with existing call centers: Use AI agents to handle peak loads and resolve frequently asked repetitive inquiries, allowing human resources to focus on complex individual cases.
Industries prioritizing reliability: Sectors like finance and healthcare, which have high requirements for call stability and compliance, need carrier-grade guarantees.
Teams looking to build custom voice workflows: Orchestrate complex conversation logic through a multi-agent system to flexibly adapt to business branches.
Global operation entities: Ensure consistent and stable call quality for customers worldwide through low latency and regional delivery.

Key features

Visual process building

Use Flow Designer to define the logic of each step and connect interfaces, enabling the agent to act based on business rules rather than guesses.

BELL Deployment Framework

Connects the four phases of Build, Evaluate, Launch, and Learn into a closed loop, reducing launch risks and continuously optimizing performance.

Built-in communication network: The self-developed telephone line provides sub-100-millisecond latency and carrier-grade reliability, eliminating the need to replace existing SIP or PBX devices.

Test Sandbox

Evaluate accuracy, response quality and compliance through simulated calls in the Test Center and verify the agent's performance before official customer service.

Real-time monitoring and fine-tuning: Conduct automatic quality inspection and analyze every conversation after launch, feed back intents and accuracy to the next version, and achieve continuous improvement.

How to use Synthflow AI

1Start with the BELL framework: Follow the four steps of Build, Evaluate, Launch, and Learn. Do not skip the evaluation phase and launch production directly to avoid losing control.
2Start with high-frequency scenarios: Automate the businesses with the most fixed Q&A first, accumulate data, and then expand to more open-ended conversations.
3Leverage sandbox regression testing: Simulate calls in the sandbox before each update, confirm compliance with standards before release, and avoid impacting real customers.
4Monitor key metrics: Keep an eye on answer rate, accuracy and satisfaction, and use real conversations to feed back into training and process iteration.
5Retain manual handoff: Set up rules for transferring to human agents for complex or emotional calls, with AI handling initial routing and information collection.
