Speech Tuner


LumenVox Speech Tuner Features

The LumenVox Speech Tuner is a complete maintenance tool that performs transcription and application fine-tuning. It also allows for instant parameter, grammar and version upgrade testing with any LumenVox Product. It reduces the work of your post-deployment application revisions, and allows you to bring tuning in-house for producing a cost effective speech solution.


Application Tuning - Improve Speech Application Performance

Without regular cycles of tuning, most speech applications are destined to suffer from the same problems, leading to unhappy users. Tuning resolves that by allowing administrators the ability to correct mistakes in their application. The LumenVox Speech Tuner’s Windows graphical user interface allows you to review vital accuracy statistics right from your Windows desktop, putting important information in a familiar interface.

Database Loading - Faster, More User-Friendly Database Loading

Converters import call log data into the LumenVox Speech Tuner database. All the information stored in the call log is available in the Speech Tuner, putting the data you need only a click away.

Call Browser

Easy access to all calls. The Call Browser displays a list of currently loaded and filtered calls and displays all the interactions for a selected call.


Quickly choose and listen to a specific interaction.

Export the audio file all from the same window.


Grammar Tester - Instantly Check Results of Proposed Grammar Changes

The LumenVox Speech Tuner Tester allows users to instantly see how proposed changes to grammar or Speech Engine configurations will affect the results of the speech application. It makes changing grammars or other Speech Engine parameters secure, faster, and more accurate. The Speech Tuner allows you to use historical data to validate changes, ensuring the creation of a successful application.


Transcriber - Makes Transcription Easy

Transcribing speech is an excellent way to analyze how callers interact with the system. Transcriptions are used to calculate automatic performance measurements such as in-grammar or out-of-grammar rates and recognition accuracy. Good transcripts enable the Speech Tuner to adjust the speech recognition application as needed. The LumenVox Speech Tuner Transcriber is designed to make this process quick and seamless with improved statistics, easy to use control panel interface, and shortcuts.

Text-To-Speech Engine Support

A counterpart to LumenVox Text-to-Speech (TTS) Engine, the LumenVox Speech Tuner allows users to fine-tune LumenVox TTS settings,


View and edit SSML documents, and preview TTS output.
