Speech recognition for the AI age.



Intelligent Voice indexes key words and phrases from your telephone calls



This allows you to search for telephone calls as if they were text.



Add-on modules give you the power to analyze calls and track anomalous behavior.



Nvidia® GPU technology processes calls at up to 400x faster than real time.


How smart are yours?


Intelligent Voice® boosts the intelligence of your calls, and puts them to work for you.


MifidII & GDPR compliance nightmares? Make your fears disappear. Store & search all your voice data using the sound of voice.

Banish the Compliance Monster.

Without the ability to index and search the content of your company’s calls, the simplest inquiry from a regulator, e-discovery, or Freedom Of Information Act Request that applies to voice, can mean trouble. It can mean big, expensive, time-consuming trouble of manually wading—actually listening—through hundreds or thousands of hours of calls.

The alternative? Call Recording and Compliance software by Intelligent Voice.
With IV, you can have ready-access to all of your data, giving you the ability to pinpoint what was verbally said on a call, when, to whom, and by whom using voice indexing —as easily as searching for text. Make better use of your compliance team’s resources.

IV’s got you covered.


Bogged down by audio? Search hours of recordings with a click. IV’s e-Discovery is the key.


Imagine: agent voice call and screen data you can search—live, and post-call. IV’s got it. Get it and get ahead.

You can’t improve what you can’t measure.

Call centers have become wizards at measuring data around calls: call and hold times, conversion and retention rates, and more. But attempts to measure the core of the call center world—the verbal content of calls—are still in baby steps. Random QA monitoring a small percentage of calls is the best technology has afforded. Until now.

Intelligent Voice for Call Centers turns what was said in every call into data that can be searched, analyzed and measured. Combine it with screen capture, and other data, to get the full picture of your business. Find and reward the true super-stars, and catch anomalous behavior before it becomes a liability—even in real time s with our “live” call monitoring.

You already record and store your calls. That’s a mountain of unused data. With IV, put your call center voice data to work for you.

Measure both: facts about each call, and what is said.


If your hot new app needs secure, private, high-speed ASR, then you need Intelligent Voice.

Let’s partner, partner.

So, you’re developing an exciting new app and you need accurate, super high-speed Automatic Speech Recognition (ASR) integrated. Don’t reinvent the wheel—unless you’ve got a few extra years and loads of extra cash to invest. We’ve done it for you.

Also, think security. If you’re sending a customer’s sensitive, private data to a public API like Google or Watson, the worry becomes: are you breaching your customer’s data privacy? Are you breaking the law?

Intelligent Voice powers your ASR and speech-to-text functions using our own AWS Azure or other cloud instance. We’ve got every avenue of speech-search covered: hyperphonic, encrypted, biometric. IV model-building means your API gets even better as it’s used, and acquires the vocabulary that is unique to each client. Let our (top quality and cost-effective) technology complement yours, and let’s create something wonderful together.

Your API is better with IV.


Credit Card Data giving you problems?  Let us clean it up, automatically

Automatically redact credit card information from both the Audio and Transcript


Intelligent Voice pick up your call recording and run it through our speech to text engine. We then we run our PCI algorithm across the transcription, if we detect PCI data it is redacted in both the audio and the transcript.

We are working alongside Zendesk to allow the redacted recording and transcript to be added to the ticket. If PCI data is not detected then the transcript is added to the ticket.

Increase your Privacy with IV

Make the audible, searchable

And the invisible, visible.


Intelligent Voice® takes your company’s phone calls (+ email and IM) and turns them into smart data using “World’s Fastest” Speech to Text Engine.

High-speed ASR

Lightning-fast speech-to-text

High-speed ASR

Automatic speech recognition (ASR) technology is how you turn the spoken word into valuable data you can use. Intelligent Voice has developed high-speed, secure, private ASR that is not only cutting edge, but ready to plug into to your existing phone and data systems. With IV, you can quickly and easily turn what is said on the phone into data you can search, with a click of your mouse.

Live call monitoring

Catch anomalies, real-time

Live call monitoring

‘Live Call Monitoring’ no longer means you must physically sit, or pay someone to sit, and listen to one live call at a time. Human quality assurance may still have its place. But IV offers Live Call Monitoring that goes beyond, far beyond individual QA. Until now, there hasn’t been a way to perform real-time monitoring to all your company calls. Whether in a call center environment or any other, with Intelligent Voice’s Live Call Monitoring, you can be plugged into all your calls as they happen, and be alerted about anomalous behavior as it occurs.

IVNote + SmartTranscript

Search what’s said

IVNote + SmartTranscript

With each call, your IV Technology creates an HTML file, a SmartTranscript, that generates a written record of what was said. It not only transcribes and indexes the call, but is also linked to the call recording and audio player. Clicking on any of the words in the SmartTranscript allows you to JumpTo that specific part of the call, and listen for yourself. With Intelligent Voice, you can search for key terms in a specific call or in your entire archive of SmartTranscript call data.

IVNOTE is for everyone who’s ever wished they could get more out of their phone calls. IVNOTE is simple. It captures your phone calls, turns them into text, and sends the transcript and the call directly to your inbox. You can be more present in calls, be more engaged in the conversation, ask more relevant questions—if half of your attention and mental energy aren’t spent notetaking and trying to track what was said for future reference. Be there fully. Let us track the important points of what was said for you. 


Accelerates ‘learning’ & accuracy


Language is a living thing. We all have specific vocabulary that we favor—and it often changes over time. Whether it’s specific work-related terminology or evolving expressions in our personal and cultural lexicon, Intelligent Voice’s language model-building helps the technology “learn” your frequently used terms, for the most accurate transcripts possible. Also, our acoustic modeling trains the system to recognize and best adjust to different sounds, like background noise, phone and microphone setup, to best hone in on voices and clearly capture what is said.

API-based integration

Let our features enhance yours.

API-based integration

Increasingly, and especially since Siri, customers expect their apps to respond to the human voice. Intelligent Voice has what IT developers need to drive their app’s features. Partner with us to give your program interface the voice-enabled functionality your customers want. Our technology is easy to incorporate. Our team of experts is flexible, and eager to help our creation bring yours to life. Whether it’s automatic speech recognition, speech-to-text, recording, indexing, model-building, biometric, hyperphonic or encrypted voice data search—our solutions deliver industry-leading accuracy, speed, and security.

On-site or in-cloud

Choose where your data ‘lives’

On-site or in-cloud

While Intelligent Voice turns your phone calls into searchable data—you control where and how that data is stored. Whether you want the flexibility, cost-effectiveness, and quick scalability of hosting your voice data in the cloud, or if you have the expertise and want the added security and control of hosting your data on site, or whether you choose to have your voice data hosted by a third party, IV accommodates. Intelligent Voice helps you find hosting for your voice data that’s right for you.

Are you in the loop on Audio Review? See you at #Relativityfest 2018

Where has the year gone, we are all set to exhibit at our 2nd Relativity Fest in Chicago. This time last year we were new to the scene and were blown away by the event. The format, the content, the sponsors and most importantly the attendees were all fantastic.


We felt that last year was such a huge success, for us, but also for Relativity. The word most commonly used on our stand was “WOW”, which was a personal highlight of our head of global sales Colin Foster, who was on the receiving end of this more than once after one of his demos.


Last year we were invited to show our SmartTranscript™ plugin. If you  don’t know already, our SmartTranscript is a standalone HTML5 object which is a drop in replacement for original WAV/MP3 files containing everything a reviewer needs (Audio, JumpTo™ Topics and Transcriptions) in one single file.


Audio review within Relativity was not intuitive and being able to utilise SmartTranscript within the Relativity Platform has become invaluable to users.


As you can imagine, following the success of our initial integration, we have not sat still and have seen a lot of progress in improving how audio is managed within Relativity.  Intelligent Voice’s main mission is to help organisations uncover the hidden truth in their data: this is particularly true of data sources that are historically put into the “too hard” pile, such as telephone calls and IM chat.

New this year we have a number of exciting developments.


NEW: Audio Viewer for Relativity One:


Intelligent Voice’s Smart Transcript is now available for use with RelativityOne. You can analyse and search audio files without leaving the platform. With Intelligent Voice, you can search for key terms in a specific audio file or in your entire archive of audio data.  Persistent Search Terms are identified on the right hand side automatically.


The Intelligent Voice Audio Viewer presents a written record of an audio file. It not only transcribes and indexes the audio, but is also linked to the original recording and audio player. Clicking on any of the keywords in the Audio Viewer will allow you to JumpTo that specific part of the audio, and listen for yourself.


Audio Review Screenshot

The viewer is currently available for standalone SmartTranscripts, and pre-transcribed audio in Relativity and Relativity One.  Very soon it will work in conjunction with the existing SmartAudio™ Plugin which allows you to transcribe and audio or video on the fly.


SmartAudio™ for Relativity:


Intelligent Voice lets you ingest and search Audio directly in Relativity. Built from the ground up with data security in mind, Intelligent Voice lets you choose on-prem, private cloud or partner  hosted processing using our unique ultra-high-speed GPU powered speech recognition algorithms.


Working across more than a dozen languages and dialects, Intelligent Voice’s market-leading SmartTranscript technology cuts review time by 70%. in addition, Intelligent Voice provides an in-Relativity alternative word (“Lattice”) search to enable you to find likely words and phrases without the over-retrieval of phonetic search.


User-driven model improvement puts the power to get greater accuracy in your hands without the need for expensive and time-consuming professional services. And Intelligent Voice’s biometric search capability is now integrated into the core product to allow you to identify relevant audio files, just from the sound of the human voice.




IV Connect


Intelligent Voice is not tied into any on voice recording platform or email archive or messaging provider. This has allowed IV to develop connectors to a wide range of systems, which in turn allows its customer to move from one provider to another without lock-in.


IV CONNECT takes your data such as telephone calls, Email, IM chat and Audio Data Sources and normalises it so it can be pushed directly into Relativity. Intelligent Voice’s deep connection and processing capability allows for all data to flow direct into Relativity and be search ready for your review and analysis.


 We will be performing demos on the stand throughout Relativity Fest, so pop by and have a chat to find out more.
