Re: Inserting Latency in NVDA Speech and Bluetooth Audio

Tony Malykh

On the other hand, if you are looking into switching to bluetooth headphones, I would strongly recommend to look into APTX LL bluetooth codec - it works with only 30ms latency - not noticeable by human ear. You'd need to buy a transmitter that supports it and headphones that support it. I have been using this configuration for years and it is well worth it. If you're interested - ping me offline - I think admins here don't like topics not related to NVDA.

Dear all,

This may come off as an odd request, but I do need it to simulate a
certain scenario. I would like to have NVDA's speech - with the same
voice settings and my same ESpeak-NG - be outputted but with a delay
of 150 ms. Latency is generally frowned upon, yes, but I would like to
artificially manufacture it at present. Is there some way of doing

For context, I am aware that standard Bluetooth audio (sans low
latency audio codecs) typically have an associated latency of 150-250
ms. Since I do not have the required equipment to test that
practically, I want to emulate that latency with NVDA on my laptop
speakers so as to get a sense of how much a couple hundred
milliseconds of delay is likely to affect me in the real world.
