I have an audio annotation task that is focused on applying multiple (occasionally overlapping) classes to speech regions. It would be extremely helpful to be able to accelerate or decelerate the playback rate to make it easier for annotators to carefully specify onset/offset boundaries, especially in areas of overlapping speakers.
Is this possible, whether out of the box or through some workaround? I've only been able to find this mention of an
audio_rate configuration parameter, but no discussion of whether there's a way to update that on the fly as opposed to setting it once at the outset of the session and then just living with it.
