The Problem of Robotic Voice When Changing Speech Speed - From Phase Vocoder to WSOLA
Our take: Audio processing solution (WSOLA); solid technique but tutorial-format, niche problem.
Why Impact & Innovation? We ask two questions of every story: did this actually change something in the real world (Impact), and is the idea genuinely new (Innovation)? Together, that's the TS Score — not engagement, not who posted it, just what matters and what's new.
Time-stretching audio with librosa's phase vocoder causes robotic artifacts due to phase blurring, which can be resolved by implementing WSOLA (Waveform Similarity Overlap-Add) from scratch.
