Audio and video recordings are now increasingly common in both criminal and enterprise investigations. Voice messages, call recordings, and video files can contain critical communications, including mentions of pertinent information, agreements, or harassment — yet listening to hours of recordings is neither practical nor sustainable, especially when multiple languages are involved.
Belkasoft has published a new guide detailing how BelkaGPT, the AI assistant built into Belkasoft X, handles automatic speech recognition (ASR) in digital forensic and incident response workflows.
Automatic Speech Recognition
BelkaGPT transcribes audio and video recordings directly within Belkasoft X, supporting European, Asian, and Semitic languages. Transcripts include timestamps, so investigators can quickly navigate to the relevant parts of a recording to verify the output. ASR can run automatically when a data source is added to a case, or on selected items and filtered subsets — giving investigators full control over when and what to process.
Natural Language Search Across Transcripts
Once recordings are transcribed, investigators can query them in plain language. BelkaGPT understands context, so it can surface implied meanings and indirect references — not just exact word matches. Ask, “Are there any mentions of investment fraud?” or “Find voice messages containing threats,” and BelkaGPT retrieves the most relevant results from across the case data.
Multilingual Evidence Discovery
In multilingual cases, BelkaGPT’s ability to query transcripts across languages is a significant advantage. The article includes a practical example showing how querying in the same language as the target content — rather than defaulting to English — can surface evidence that would otherwise be missed.
