Secure Speech and NLP Solutions. Make sense of your data.

Our advanced Generative AI technology sets us apart. We utilise the latest breakthroughs in artificial intelligence to ensure the highest quality transcriptions and analysis. Our algorithms are continually refined to offer you the most accurate and efficient results.



Receive and utilise short summaries of entire conversations and the topics discussed to help build a simple understanding of large amounts of speech.

Behavioural Marker Detection

Easily identify disfluencies, temporal lacunae and a host of other behavioural “tics” that can be deployed in conjunction with a rules-based LLM model to help identify fraud and other unwanted behaviours.


Identify and label different speakers in an audio recording using advanced AI-powered clustering technology.

Topic Extraction

Automatically identify and extract specific topics or themes from your data.

Rules-Based LLMs

Guard against hallucinations and false results by imposing strict rules on input and output for a range of Large Language Models (LLMs) to satisfy critical internal use cases.

Language ID

Understand multiple languages from the same call or meeting, to capture “code switching” and loan words.

Easy Tuning

Your organisation’s ‘voice’ is unique: We allow you to quickly adapt models to domain-specific languages, to cope with digital comms, home and hybrid working, multilingual employees and more.

Video OCR

Optical Character Recognition (OCR) allows speech to text transcription from videos, whether that’s a Zoom call, presentation or a shared screen.

Text & Voice Based Sentiment

AI-based technology uses NLP and machine learning to appraise each speaker in a conversation, tracking changes in feeling and scoring speakers accordingly in alignment with their behaviours in relation to specific topics and themes.


AI powered speech to text, powered by the latest algorithms. We were first to market with GPU accelerated speech recognition in 2014.

Voice Identity Management

Search for people based on voice samples, validate speaker identity, enhance metadata and ensure attribution.

Smart Transcription

Instead of trawling through hours of recorded speech, use Smart Transcripts with searchable features to help identify and locate speech around key topics and themes.

NLP (Natural Language Processing)

Our AI understands text and spoken words like a human, fully grasping the meaning and human behaviours.

We see Intelligent Voice as the leader in audio processing in the legal market, not just in terms of accuracy, but because they really understand the difficulties that audio presents and the user needs. They have worked hard to make audio processing more than just ‘OCR for Voice’, and instead have built the ability to make audio as reviewable as text
