UnverifiedThe Mel spectrogram simulates the nonlinear perceptual characteristics of the human ear across different frequencies, converting raw audio waveforms into a two-dimensional time-frequency representation that is convenient for convolutional neural networks to perform pattern recognition.74% similarUnverified标准Whisper模型在处理歌声时准确率会下降，社区开发了whisper-timestamped等变体实现逐词级别时间轴对齐73% similarUnverifiedMel频谱图基于心理声学研究，通过对数变换模拟人耳对低频比高频更敏感的非线性感知特性71% similarUnverifiedResearch shows that Whisper's probability of hallucination is particularly prominent during silent segments, producing fluent transcription results whose content does not match the original audio.70% similarUnverified端到端音频模型可能在音频层面产生幻觉，即生成训练数据中存在但与当前语境无关的音频片段69% similar
