Speech Technology Center

Professional hardware and software suite for speech signal analysis. Since it has been launched in 1992, IKAR Lab has evolved from a sound editor application to the most popular audio forensic lab in the world. Today it is serving experts in 350 laboratories in more than 40 countries worldwide.

Main Features

Visualization

Draw FFT or LPC sonograms, adjust brightness, contrast or normalization. Choose the proper frame size, weighting windows and other parameters on the fly. Or you can use default presets. Use spectrum in the point to overlay formants to comparison more visual. Draw cepstrum for pitch and melodic pattern analysis.

TEXT TRANSCRIPTION AND SPEECH SEGMENTATION

Selected audio fragments can be easily assigned to particular categories (e.g. different speakers or sounds) and speech fragments can be transcribed and displayed as text.


Processing

IKAR Lab provides a wide variety of expert editing and signal processing tools that improve the intelligibility of recorded speech and prepare audio recordings for further analysis. Functionalities include:
Signal normalization & Balancing
Speaker & Stereo separation
Linear transformation
Re-sampling & Modulation
Bit depth conversion
Tempo correction (without pitch distortion)
Adaptive broadband noise filter
Adaptive inverse filter
Adaptive harmonic filter
Merging two mono to stereo
Pseudo-stereo

Multi-window Interface

Multi-window interface makes signal comparison easy. Several audio files and their visual representations can be opened in different windows and positioned according to particular tasks: vertically for identification purposes, horizontally for authentication and noise reduction or customized according to user preference. Signals can be layered for easy comparison. Colors and transparency can be changed to ease readability.

DETECTING SPEECH AND NOISES

The speech detector automatically marks speech fragments in the audio signal that are suitable for identification. The module can also be configured to detect noisy areas: dial tones, clipped fragments, and clicks.

SIGNAL ANALYSIS

IKAR Lab's software can automatically calculate the following signal characteristics:
Frequency response
Signal-to-noise ratio
Reverberation time
Clipping and tonal noises
Pure speech signal duration

SPEAKER MARKING

IKAR Lab allows you to automatically detect speech fragments pronounced by two different speakers and to mark them accordingly
