9 Best Voice Analysis Software in 2021

What is voice analysis software?

Voice analytics software analyses audio recordings using the biometric system. These tools are best designed for identifying speaker's voices and other such audio evidence. You can also use the software for comparing varied audio sounds aside from separating the voices of different speakers while detecting the silence.

Voice analysis software is used for criminal investigation, speech research and other educational activities. This is so because the platform undertakes critical functions such as sound and speech analysis as well as sound transcription and annotations.

Voice analysis procedures require accurate waveform and frequency analysis along with critical listening. The software analyses voices in an in-depth manner keeping the above parameters in view to ensure the correct outcome.

Features of Voice Analysis software

Identifying different speech samples in any audio recording for recognizing the speaker is easy with voice analytical tools. Gender, demographic variables and even accent aren't a hindrance when it comes to speech detection capabilities of the voice analysis software. Let us look at other such features that make voice identification software essential for forensic experts, music teachers, speech therapists, etc.

• Spectrogram trace

Spectrogram trace within voice analysis software is used for comparing sound harmonics and formants. Such comparisons are essential for understanding speech articulation, vocal resonance and glottic abduction. The feature can be used in both narrow as well as wideband and is especially critical for making changes in sound gain and levels.

• Speech-silence detection

Voice identification software is critical for identifying the different parts of silence and speech in an audio file. These can be easily checked, verified and manually corrected with vocal analysis software for speech enhancement.

• Likelihood ratio calculation

Likelihood ratio calculations are score based calculations used for evidence purposes just like fingerprinting and handwriting. These are combined with vowel formants in phonetic-acoustic assessments for measuring the strength of evidence. The likelihood ratio calculation in voice analysis applications are based on harmonized models and validated scripts.

• Speaker identification

Layered voice analysis software solutions are especially useful in criminal cases. With the software's advanced speaker identification and voice analysis tool, the speaker's voice can be automatically detected in the most unbiased manner.

• Analyze pitch & volume

Voice inspection tools are good at recognizing unique voiceprints without any barrier of language support. Through such objective voice assessments, it is easy to analyze pitch and volume in any recording. You can also compare different voice recordings with the support of this feature.

• Wave editor

Wave editor helps in cutting through noises quickly so that detecting the audio section within such recordings is easy. You can further ease this process by adding a spectrogram for deeper analysis. In case audio is completely inaudible for voice analysis, you have the option of flagging it.

• Case management

The more organized your work is, the better would be the outcome. Layered voice analysis software helps in systematically organizing your audio files as per the criteria like corresponding sets, population sets, etc.

Who All Can Benefit from Voice Analysis Software?

Analyze several audio files in minutes for the speaker's identification and voice treatment with voice identification software. With the software's intuitive interface, it is easy to organize audio files for future reference. You can trust the reference population management functionality of layered voice analysis software to analyze voices against reference populations. The reference population comprises batches of samples that are organized according to language, gender and such demographic indicators.

• Speech Therapists
• Music Teachers
• Music & Singing Students
• Instrument Builders
• Forensic experts
• Call center agents
• Physicians
• Law firms
• Contractors
• People with neurological conditions
• Pathologists

Call center voice analysis software provides other key functions along with speech recognition, such as email and document transcriber, multiple language speech detectors, recording dictation, audio capture and editing tools. Voice analysis software is one of the most advanced technological innovations for audio/video to text conversion, actionable business insight, documentation, task planning, or any other technicality that best suits your company's requirements.

What Speech Features Can Be Analysed with Voice Analysis Tools?

Whether it is about interpreting human speech for transcribing it into text or translating the text into speech, performing these functions is easy with voice analysis apps. The other speech features that you can analyze using the software are:

• Jitter
• Shimmer
• Harmonic-to-Noise ratio
• Maximum phonation time
• Fundamental frequency deviation from the standard
