Voice Inspector 5.2

Voice Inspector 5.2.0, BSAPI 3.61.0 (2024-04-04)

  • New: New Case wizard checks for presence of Questioned and Reference recordings
  • New: Number of audio channels is displayed in
    • Case view
    • Recording details view
    • Score table view
    • Report 
  • Fixed: Application crash with phoneme search
  • Fixed: Generalized logistic distribution for Suspected speaker vs. Suspected speaker Target score distribution
  • Fixed: Population Set selected correctly even if renamed in the selection window
  • Improved: Speech length display in the case view: added “Unlimited” option to display the speech length permanently

  • Removed: Speech length compensation
Voice Inspector 5.1

Voice Inspector 5.1.0, BSAPI 3.60.0 (2023-12-07)

  • New: A generalized logistic distribution function is added as a default option. The Gaussian distribution function is preserved as the secondary option. The figure below shows both probability distribution functions applied to the same data set.

    Figure 1: shows both probability distribution functions and demonstrates that generalized logistic PDF can more accurately model a skewed distribution. Such skewed distributions are being produced by the modern highly accurate speaker identification system of Phonexia.
  • Fixed: Audio files with Unicode characters in their name can be also opened on Windows.
  • Changed: The histogram bins in the probability density function plot are now normalized.
  • Changed: The case description (field in the information table on the left when selecting a case) is now editable.
  • Changed: The description of the act and the Conclusion of the case can be edited from the case information table.
  • Improved: Copying from chart values table is enhanced – added header to copied data, added Ctrl+C keyboard shortcut to copy table data.
  • Improved: Report template is enhanced for all included languages – improved report layout, easier CSS styling via style.css, added new report variables for Expert and Organization
Voice Inspector 5.0

Voice Inspector 5.0.0, BSAPI 3.57.0 (2023-06-20)

  • New: Speaker Identification XL5 technology model
  • New: Data in lists/tables are now sorted alphabetically
  • New: Enlarge the initial set of speakers included in examples; some of the speakers are multilingual

❗❗❗ Voice Inspector 5.0 requires a new license.
To upgrade from version 4 or 3, please contact the Phonexia sales representative.

Phonexia Voice Inspector 5.0 brings a Speaker Identification model XL5, that provides more accurate results for telephony data in comparison with previous generations of Speaker Identification models such as SID4 XL4. Users can observe that the SID4 XL5 model returns different values of LLR scores which are used for evidence calculation. Therefore Speaker Identification score distribution for the population sets differs from previous generations. One of the identified differences is a higher discriminability of target and non-target scores. See an example of score distributions applied to the same population set below.
