摘要:

我们比较了一系列的时间压缩方法适用于正常和清晰的语音。首先,我们评估一个线性(统一)的方法适用于这些风格,以及自然产生的快速语音。我们发现,与文献一致,未处理的快速语音比线性压缩的正常语音更难理解。快速语音也比压缩清晰语音更难理解,但在最高速率(比正常速度快三倍)时,清晰语音相对于快速语音的优势就丧失了。为了测试这是否是由于较短的语音持续时间,我们评估,在我们的第二个实验中,一系列的方法,以不同的速度压缩语音和沉默。我们发现,即使当语音和沉默的整体持续时间在不同风格中保持相同时,压缩的正常语音仍然比压缩的清晰语音更容易理解。压缩沉默的两倍,语音改善结果进一步为正常的语音很少的额外的计算成本。

英文摘要:

We compare a series of time compression methods applied to normal and clear speech. First we evaluate a linear (uniform) method applied to these styles as well as to naturally-produced fast speech. We found, in line with the literature, that unprocessed fast speech was less intelligible than linearly compressed normal speech. Fast speech was also less intelligible than compressed clear speech but at the highest rate (three times faster than normal) the advantage of clear over fast speech was lost. To test whether this was due to shorter speech duration we evaluate, in our second experiments, a range of methods that compress speech and silence at different rates. We found that even when the overall duration of speech and silence is kept the same across styles, compressed normal speech is still more intelligible than compressed clear speech. Compressing silence twice as much as speech improved results further for normal speech with very little additional computational costs.
