yay! + another conditional speed/skip based on content? (#899 (comment) )

• technically simple implemenation: Dynamic speed based on speed of speech (syllables per minute or wpm) & difficulty (average letters per word) (based on transcript & category - not audio)

• hi @vantezzen https://github.com/vantezzen/skip-silence (MIT license!)

What kinds of silences are typical?

1. phonetics (& necessary physiology). ~<0.7 seconds each. Some of these pauses make words(/phrases) more recognizable or just familiar (even if their origin would be physiology/hard to avoid physically).

• So if some of these could be skipped to save time efficiently, removing others might increase listening-difficulty/listening-errors.

2. category dependend error. I.e. in Live stream & recordings of lectures.
   The less scripted the sound / talk was, the more likely there are pauses due to human error, lack of performance/exhaustion of the speaker, combined with 'um'- & 'hm'-sounds (or other errors, like mono Mono audio(IDEA) #552).

• if such category is detected, then the remedy can be much more specific/confident.

3. 0.5s-10s rethorics (like minute/s of silence, to express relevance solemnly/diginity/equanimity)

• hard to decide. maybe easier by category or by channel

4. several seconds or minutes: broken sound/error, silent scenes/videos(no sound existing), art

• these can be skipped in inactive tabs more likely meaningfully than in active ones.

• in active, visible tabs, all silence-skipping could(?) analyze video too. ( - Video frames should not change much noticably during the whole skipped period)

• 6. Exclusion/s: Music, .., ... ?

On 1. : Is all existing (proportional) digital speed-up only skipping random parts?
"Micro silences" appearing everywhere, could be removed from every syllable or word in a speech, without changing their proportional tempo. Thus changing how the speaker's energy is perceived, but no changing the clarity of words as much - nor the relational speed (pauses might be semantically relevant. )

• I.e. maybe cutting 10% of the duration of each unit of speech (1x syllable/word+ 1x pause)
  • This might, range from 0.2s to 0.6s usually for one speaker/video (up to 10 seconds rethorically, rarely)
    In this case maybe each could be shortned by 10%. i.e. 0.09s to 0.54s (up to 4.5s).
    • Could be applied to music more obviously, if every beat can be 0.5seconds duration, and might include at least 0.05s in silence/s between the notes played or syllables sung during that beat. ( - Yet the single beat or word might change the rythm wihin)

We should skip it .

2. category dependent error. I.e. in Live stream & recordings of lectures.

I don't think it is needed. Frame may change a lot during a segment which is intended to be skipped and hence create too many false positive.

• these can be skipped in inactive tabs more likely meaningfully than in active ones.

we should skip it in both active and inactive ones .

5. Exclusion/s: Music, .., ... ?

Of course, if easily possible. May provide opt-out option for disabling skip silence in music .

Micro silences" appearing everywhere,

May provide opt-in option for enabling micro silence skipping or just do it by default and not provide option to opt-out of it .
as I think skip silence is absolute skip silence to save time .

• less complicated feature idea: dynamic speed based on speed of speech (syllables per minute or wpm)

Yeah, it is very easy if there are captions in the video .

• dynamic speed based on speed of speech (syllables per minute or wpm

How will we calculate the WPM in the video that don't have captions ?

*why would you want to skip when a lot is happening in the video and the tab is active too? (i.e. new scene, completely different backgrounds)

I just thought it will quite complicated and performance inefficient, So, I had said that.

in my experience with listening to 2000h+ of podcasts per year: skipping silence becomes a non-issue and even annoying when you have the proper playback speed set (for me 2.3..3.0x, but there's a legend of a 8.0x user )

By the way, Google podcast also have a option to skip silence but YouTube does not.

Added skipping silence to the list of player buttons we should add, so that it can just be activated per video or mood. #1445
(While each button on right-click could allow to build specific sticky rules 'always for this channel' / category / ..

Hi guys! @allanlaal what about 0.8x while working?
@chirag127 ...performance, yes. Just tried to be complete ☺
