Task #4211
Updated by Tihelka Dan almost 7 years ago
This has been suggested in #4176: bq. We can try experimenting with some spectral slope measures. These typically compare energy in specific spectral bands. I would try the measure which Honza Volín introduced, which calculates the ratio of a low and high frequency band energy. The low band is defined as 350-1100 Hz (so it excludes the band corresponding to F0), the high band includes the 2300-5500 Hz frequency range (excluding the F2 range, which is important to convey phonemic differences). Thus, we need spectral slope values computed somehow. Radek S. suggested that _"In Praat, you can use the command Get band energy difference... 350 1100 2300 5500."_ Could you, please, have a look at such slopes computation? For _spkr_AJ_ now (and store them to @data/non-mastered/zkracene-pauzy/param/spectral-slopes/@). For more details about slopes computation contact Radek or Tomáš, or see *#971* where some description of spectral slopes is given. Tomáš.
