Accelerate customer experience innovation and cut contact center costs

Gyst is a real-time voice API that tunes every call across your IVR and LLM / agentic-AI voicebots, increasing self-service and cutting handle time without rewriting your stack.


"I've never seen any other technology start producing results so quickly - a lot of bang for very low risk"

ADVANCED VOICE PERSONALIZATION

Increase call automation and reduce handle times with the voice platform you already have

Gyst uses machine learning, advanced algorithms, and generative AI to measure, analyze, and optimize every call in real time. For each turn in the dialog, Gyst adjusts playback speed, timeouts, input method, and prompts based on how the caller is actually behaving—whether they are an expert moving fast, distracted on a mobile phone, or a first-time user who needs more time.

Key features of Gyst’s advanced voice personalization:
  • Adaptive Playback Control - Dynamically adjusts audio speed at every conversation turn based on caller skills.
  • Intelligent Opt Out - Tracks caller progress and seamlessly transfers them to an agent or another channel before frustration builds.
  • Smart Modality Switching - Offers speech-only, touch-tone-only, or both options based on what works best for the caller.
  • Intelligent Timeout Control - Provides extra time for struggling callers to respond to voice prompts when needed.
  • Machine-Learned Audio Prompts - Provides additional audio instructions for callers struggling in the voice channel.
  • Machine-Learned Audio Playback - Slows down audio playback at interaction points where callers typically struggle.
  • Generative AI Prompts - Refines customer experience adjustments using advanced algorithms based on caller behavior and the calling environment.


"I am really impressed that a company has come up with this amazingly clever and meaningful product"

ADVANCED VOICE PERSONALIZATION

A web API that auto-personalizes your IVR and voicebots

‍The Gyst Web API plugs into your existing contact-center stack—IVR, voicebots, and agentic-AI experiences—through a simple HTTPS call. On every dialog turn it returns tuned playback speed, timeout guidance, and prompt hints in real time, without storing caller profiles.

Full API specs and examples are published as Postman collections, so your developers can explore and test Gyst in minutes. The API supports simple GET calls for quick trials and richer POST integrations for production traffic.


"This technology incorporates an exceedingly clever and intrinsically valuable idea."

FOR AMAZON CONNECT

Gyst for Amazon Connect Contact Centers

Gyst plugs into your Amazon Connect flows through a simple web API call. The same API works with Amazon Lex and Bedrock / Nova–based voice agents, so you can add real-time tuning without rewriting call flows. Gyst’s optimization layer sits alongside your IVR or conversational AI, applying our adaptive playback, timeout, opt-out, and behavioral analytics to every interaction.

By implementing Gyst, you quickly see how callers actually move through your current experiences and how changes impact behavior over time. Gyst dynamically delivers the right CX parameters for each caller in real time, helping Amazon Connect customers increase self-service, reduce handle time, and de-risk modernization projects.

Key Benefits:

  • Platform-agnostic implementation – Works with Amazon Connect today and other cloud, premise, or hybrid contact center platforms via the same web API.
  • Secure and Scalable - Designed for enterprise reliability, privacy-aware by design, and built on AWS.
  • Real-Time Optimization - Adjusts CX parameters (speed, timeouts, opt-out behavior) dynamically for every caller.
  • Actionable Insights - High-resolution analytics to pinpoint friction, compare IVR vs. agentic-AI journeys, and prioritize fixes.
