Supporting code for the paper "A study on more realistic room simulation for far-field keyword spotting".

Measured RIR dataset can be downloaded here.

First install Python dependencies:

pip install -r requirements.txt

Then install code for room impulse response generation:

# pyroomacoustics
pip install pyroomacoustics
# pygsound
pip install git+https://github.com/RoyJames/pygsound

For pygsound, please refer to their project page for additional dependencies to install.

Compare computation time between pyroomacoustics and pygsound:

• Varying number of rays: profile_nrays.py
• Varying number of specular reflections / ISM order: profile_ism_order.py

Preparing RIR datasets:

• Split original data into train and dev sets: create_measured_room_data_split.py
• Simulate measured rooms based on metadata: simulate_measured_room_dataset.py
