The automation provided by Speech Recognition can save your business significant time and resources, with a tangible impact on your profitability. It can also revolutionize your customer experience by enabling self-service, enhancing the value offered in your contact center, and augmenting the usability of your speech applications.

All these attributes drive revenue growth. But if yours is the kind of organization that views success as a process rather than an end state, why let the advantages end there? With Speech Tuning, you can eternally optimize your Speech Recognition capabilities. 

Born out of the belief that no matter how good technology is, it can always get better, Speech Tuning is the process of continually improving applications, including Automatic Speech Recognition-based systems, after they have been deployed. While this may sound like a chore, rather view Speech Tuning as an excellent opportunity to ensure the efficacy of your applications, maintain your competitive edge and amplify your Speech Recognition ROI.

The reality is: everything around us is evolving at a continuous pace. This includes your customers, the world they live in, their language and, most importantly, their expectations. You simply can’t stand still and expect to remain relevant.

If you’re not familiar with the term, Speech Tuning is a technology-driven approach to refining the performance of your speech-enabled applications, based on data gathered from real-world use. The goal is to perpetually enhance recognition accuracy, with a direct impact on call completion rates, containment rates, user experience scores and other metrics that matter to your business.

Fast, Accurate and Powerful Tuning with the LumenVox Speech Tuner

The LumenVox Speech Tuner is a complete tuning and maintenance tool and can be used to improve the effectiveness of any LumenVox product, including Automated Speech Recognizer, Text-to-Speech and more.

This tool offers value on multiple levels. First of all, it is designed to drive a swift and seamless tuning process. This allows applications to be tuned in less time with less effort, which lowers the total cost of ownership (TCO) of your speech applications. 

There are also benefits for your users. The LumenVox Speech Tuner allows you to find and improve issues that you might otherwise have overlooked. This improves CX and strengthens your brand credibility.

How Speech Tuning for Automatic Speech Recognition Works

Speech Tuning assesses how users interact with the system and its testing changes. The process takes time, but when it comes to speech, every millisecond counts. Even minute improvements in application performance produce an impactful ROI within a brief period of time. 

The LumenVox Speech Tuner performs transcriptions, instant parameter and grammar-tuning, and version upgrade-testing of any speech application. This reduces your workload during post-deployment application revisions. It also allows you to bring tuning in-house and thus avoid costly professional service fees.

LumenVox Speech Tuner is up and running, maximizing ROI, with just 3 easy steps:

1. Data Import

First, you import call log data into the Speech Tuner database. All information stored by the call log is available in the Speech Tuner. The Call Indexer service automatically scans remote speech applications for fresh logged calls, ensuring key data is just a click away.

2. Speech Transcription

Then, transcribers type the text of the caller’s speech directly into the Transcriber. Once the audio is transcribed, the Speech Tuner compares audio transcripts with the Speech Engine results to determine accuracy, greatly reducing errors associated with manual evaluations. The transcripts are evaluated using the actual decode grammar, producing measurements such as word error rates (WER), in-and out-of-grammar rates and semantic error rates.

3. Immediate Testing

Selecting an interaction in the Call Log automatically loads the associated audio and grammar into the Tester. The grammar can be edited, Speech Engine parameters set, and individual recognition tests generated. The Speech Tuner natively supports industry standard SRGS grammars. Once a set of possible changes is identified, users can batch test audio to evaluate performance, using those changes.

Ready to Reduce the TCO of Your Speech Applications?

The LumenVox Speech Tuner accelerates ROI by decreasing the time spent in tuning cycles. The more efficient your tuning process is, the more you’ll be able to decrease the Total Cost of Ownership (TCO) of your speech applications. The numbers are significant, with LumenVox clients documenting hundreds of thousands of dollars in savings per year, all as a result of fast, accurate and powerful speech tuning.
