Text-to-Speech Synthesis Techniques for MIDI-to-Audio Synthesis

Time: Wed 2021-11-03 09.00

Location: Zoom

Lecturer: Dr. Erica Cooper & Dr. Xin Wang

Speech and music audio differ in many aspects but also share
similarities. In this talk, we will discuss how speech technologies can
be applied to tasks in the music domain. We show that text-to-speech
synthesis techniques can be used for piano MIDI-to-audio synthesis
tasks, and that speaker recognition architectures can be adapted to
musical instrument recognition. For the synthesis task, Tacotron and
neural source-filter waveform models are used as the basic components
with which we build MIDI-to-audio synthesis systems in similar ways to
TTS frameworks. The subjective experimental results demonstrate that
the investigated TTS components can be applied to piano MIDI-to-audio
synthesis with minor modifications. For the instrument recognition
task, we show that the use of speaker recognition systems modified for
music can learn a meaningful embedding space that contains information
about instrument identity, as well as pitch, velocity, and playing style.
