Solutions /Forensic Voiceprint Analysis

A clear basis for comparing recordings.

From a recording to acoustic features that can be reviewed. Combine signal analysis, speech enhancement, and voiceprint comparison to assist examination, comparison, and expert assessment.

Forensic voice experts comparing waveforms, spectra, and speaker characteristics

Product features

Start with sound details
for professional examination.

Speech signal analysis

Inspect duration, sample rate, bit rate, and channels. Analyze frequency response and signal-to-noise ratio to understand the recording's basic properties.

Audio editing examination

Use speech, acoustic, and signal analysis to investigate possible edits and support recording authenticity examination.

Speaker identity comparison

Compare auditory and spectral characteristics in evidence and reference samples, documenting similarities and differences to assist speaker identity assessment.

Noise reduction and speech enhancement

Reduce background noise and improve clarity for listening and subsequent feature analysis.

Multi-speaker segmentation

Divide multi-speaker recordings into labeled segments for individual review and comparison.

Background noise analysis

Analyze background sounds to extract acoustic clues about the recording environment for expert assessment.

Case information management

Add, edit, delete, and search case records, keeping analysis connected to the relevant case.

System architecture

Deployment
that fits your business.

Assess existing examination systems, storage, and network isolation around evidence management, analysis, and comparison, then evaluate deployment and expansion.

Existing systems

Review business systems and integration needs

Network isolation

Define network conditions and isolation requirements

Business scale

Evaluate capacity and expansion requirements

Advantages

Give every comparison
a clear analytical basis.

01

Cross-analysis of multiple features

Compare auditory, spectral, and voiceprint features to provide multiple perspectives for an overall assessment.

02

Cover key examination stages

Bring signal analysis, edit detection, enhancement, and speaker comparison into one workflow.

03

Keep expert review central

The system assists analysis and comparison. Examiners form opinions using evidence, reference samples, and examination results.

04

Support future expansion

Upgrade hardware and software as examination needs change. Confirm features and deployment scope during project evaluation.

Workflow

From preparing evidence
to an overall assessment.

  1. Prepare evidence and reference samples

    Determine examination methods and plans from the assignment, then prepare recordings and equipment.

  2. Extract acoustic features

    Inspect acoustic parameters in matching or similar speech from evidence and reference recordings, identifying features and variations.

  3. Compare features

    Compare acoustic features, record similarities and differences, and prepare comparison charts.

  4. Analyze and assess

    Examiners combine results across multiple parameters to form an expert opinion.
