Query: Receiver Placement for Speech Enhancement using Sound Propagation
  Optimization   A common problem in acoustic design is the placement of speakers or receivers
for public address systems, telecommunications, and home smart speakers or
digital personal assistants. We present a novel algorithm to automatically
place a speaker or receiver in a room to improve the intelligibility of spoken
phrases in a design. Our technique uses a sound propagation optimization
formulation to maximize the Speech Transmission Index (STI) by computing an
optimal location of the sound receiver. We use an efficient and accurate hybrid
sound propagation technique on complex 3D models to compute the Room Impulse
Responses (RIR) and evaluate their impact on the STI. The overall algorithm
computes a globally optimal position of the receiver that reduces the effects
of reverberation and noise over many source positions. We evaluate our
algorithm on various indoor 3D models, all showing significant improvement in
STI, based on accurate sound propagation.
