F0 of Adolescent Speakers

First Results for the German Ph@ttSessionz Database

Chr. Draxler, F. Schiel, T. Ellbogen

BAS Bavarian Archive of Speech Signals University of Munich, Germany

SLIDE 2

Introduction

previous f0 studies of adolescents
small numbers of speakers
limited and artificial speech material,

e.g. sustained vowels

no speech data available
forensic databases
not available for German

SLIDE 3

Ph@ttSessionz: Goals

1000 speakers
50% male, 50% female (±5%)
13-19 years
good dialect coverage
recorded via Internet in secondary schools
22.05 kHz, 16 bit linear PCM, stereo

Outlook

use final release of the database
864 speakers
refine analysis
re-compute F0 for phrases
