Really depends on language, if you're writing java, you'll be putting out a lot more than that due to how stupidly verbose it is.

I also think that in writing the bottleneck is in how fast and accurate your hand can move. I would agree that English is faster than Spanish because Spanish is more verbose.

But Spanish speakers also speak faster than English speakers. This isn't the first time that a study has shown that spoken languages seem to convey data at a reliable rate, and that the verbosity of a language seems to be inversely proportional to the speed at which it's generally spoken.

From the paper [0]:

>Abstract

>Language is universal, but it has few indisputably universal characteristics, with cross-linguistic variation being the norm. For example, languages differ greatly in the number of syllables they allow, resulting in large variation in the Shannon information per syllable. Nevertheless, all natural languages allow their speakers to efficiently encode and transmit information. We show here, using quantitative methods on a large cross-linguistic corpus of 17 languages, that the coupling between language-level (information per syllable) and speaker-level (speech rate) properties results in languages encoding similar information rates (~39 bits/s) despite wide differences in each property individually: Languages are more similar in information rates than in Shannon information or speech rate. These findings highlight the intimate feedback loops between languages’ structural properties and their speakers’ neurocognition and biology under communicative pressures. Thus, language is the product of a multiscale communicative niche construction process at the intersection of biology, environment, and culture.

I can watch YouTube content at 3x without issue. I did this without much intentional effort - I simply downloaded an extension which allows me to speed up the video in increments of 0.1x using a keyboard shortcut. Whenever it felt slow I would speed it up, and whenever it felt too fast I would slow it down. Without paying much attention to the actual numbers I had reached over 3x within a month or so.

Is there a trick to get it above 2x (which is the cap in the UI). It'd be nice when watching videos of congress.

The extension he probably used is Video Speed Controller; it works on any HTML5 video, and you're not limited by whatever UI they've wrapped around that built-in functionality.

But, he says, instead of being limited by how quickly we can process information by listening, we’re likely limited by how quickly we can gather our thoughts. That’s because, he says, the average person can listen to audio recordings sped up to about 120%—and still have no problems with comprehension. Some years ago I worked on an accessibility project for an app and website designed for people with disabilities. One…

>Scientists started with written texts from 17 languages, including English, Italian, Japanese, and Vietnamese. They calculated the information density of each language in bits—the same unit that describes how quickly your cellphone, laptop, or computer modem transmits information. I feel like the whole "bits" calculation is a neat way to get into the media, but not actually related to "information density". Edit: Be…

Human speech uses the extremely dense lossy compression method called "A Lifetime of Experience and Biases"

It's only lossy when the decoder's dictionary doesn't have a similar volume of data points to properly reinflate the data stream. Things that didn't make sense to me as a teen make far too much sense now because my experience can properly contextualize the old data.

So here is my own experience. I was avid audio book fan for last 3 years and while ago some guy on reddit told me about how he listen books on Audible using high-speed option like 2.x. I never tried that before last summer since at higher speed speech become incomprehensible for me.

What this guy told me is that it's just take time to adjust to it. So I basically started to listen for books at slightly higher speed. Then I gradually increased it and in a few days I could handle 2.0x speed no problem while listening for really complex fantasy (Malazan Book of the Fallen [1]). After two weeks I could handle 2.5x without a problem.

In the beginning it was harder to comprehend at high speed while walking or crossing the street since I lost attention, but in a few months I could do anything while listening without missing any information or emotions of narrator.

To give an example of how far this can go. This spring I was listening for The Expanse audiobook [2] at 4.0x speed. With some effort I could go even faster for like 5.x in case of these particular books, but obviously can not keep up for long.

I still usually listen books at 2.0-3.0x depend on narrator and quality of audio and this skill dont go away even if I have extended time between books like a month or so.

I do it via `document.getElementsByTagName("video")[0].playbackRate = 3.0` in the dev console. You can up arrow to it similar to a normal terminal on the next video. The nice thing about this is you can put any float in e.g. 3.333.

There are also extensions of course.

The Micro Machines commercial guy was transmitting at at least 900 baud. https://www.youtube.com/watch?v=yDBvEo1s6A4
