Harness the power of Gyst for your voice applications.

Get more from your existing voice applications

Gyst can be implemented for any voice platform by calling our web API from your own voice applications.  All of the benefits of Gyst's advanced software algorithms and machine learning processes are available via this small, yet very powerful API. Implementing Gyst in this way allows you to quickly learn how your callers interact with your voice applications today, and over time as you implement seasonal and functional changes. It also allows Gyst to guide, and deliver on the fly, the ideal CX parameters for a particular customer at any given time.

We have designed Gyst from the ground up to be secure, reliable, platform agnostic, and highly scalable. We also designed it to be extremely fast and easy to use in new and existing voice applications - whether they are based on premise, in the cloud, or a via a hybrid implementation.

The API, with full documentation, is available on Postman. Postman is one of the most widely used platforms for testing and publishing web APIs and has over 20 million developers around the world. The API supports simple response/requests via the HTTP GET Method, and more detailed and powerful features via the HTTP POST Method. The best way to familiarize yourself technically with Gyst is to use the API via our collections, which are publically available on the Postman site via the links below.

Have us set up a test drive for you...

We've made it easy for you to try out Gyst with your own callers and your own voice applications. For a nominal setup cost, we will have one of our professional developers implement Gyst for you in a voice application you choose. This will allow you to prove out the savings in A/B testing against your current performance metrics. The implementation takes about 1 - 2 weeks and can usually be done using your existing contracts and volume agreements with your current cloud and/or voice service providers.

Standard features

Gyst's standard features uses machine learning and advanced algorithms to measure, analyze, and optimize the audio playback rate (words spoken per minute) for each user in real time. It does this every time the user responds to your voicebot and/or IVR. The playback rate adjustments are subtle and driven by the skill of the customer at each step of the dialog flow.

Uses machine learning to  optimize each voice session.

Speeds up audio (wpm) for users when they respond well.

Slows down audio for users when they respond poorly.

Advanced features

Gyst's advanced features allows your voicebot and IVR to dynamically adjust the response time allowed for the user to provide input at each step of the dialog flow. This really helps reduce those annoying re-prompt messages that turn your customers off and discourage the use of self-service in the voice channel. It can also make recommendations on the best mode of input (speech or touch-tone), and the optimal inflection, message content and other parameters for each individual as they progress through the call flow.

Advanced CX

Uses additional algorithms to further refine CX adjustments based on caller behavior and the calling environment.

Intelligent Opt Out

Tracks  customer progress and gets them to an agent or another channel before they get frustrated.

Smart Modality Switching

Offer speech only, touch-tone only, or both based on what works best at each conversation turn.

Personalized Response Times

Allows extra time for struggling callers to respond to your voice prompts if needed.

Personalized Audio Content

Provides additional audio instructions for callers struggling in the voice channel.

Node Adjusted Audio Speeds

Proactively slows down audio playback at interaction points most callers find difficult.
