voice | Discord Voice API for discord.js and other JS/TS libraries | Bot library

I must say the module pyttsx3 looks like it's not responding well to language changes. The synthesizer is aweful and something was missing.

Until I encountered gtts lib.

In order to get all supported languages use the following: print(gtts.lang.tts_langs())

Which will output:

found some answers to my own question, sharing with community

6-sec auto-switch mode is a new feature in Android 12, which works only if (mode == AudioSystem.MODE_IN_COMMUNICATION) (check out flow related to MSG_CHECK_MODE_FOR_UID flag). This should help for MODE_IN_COMMUNICATION set to AudioManager and left after app exit, this was messing with global/system-level audio routing. There is also a brand new AudioManager.OnModeChangedListener called when mode is (auto-)changing

and setSpeakerphoneOn turns out to be deprecated, even if this isn't marked in doc... we have new method setCommunicationDevice(AudioDeviceInfo) and in its description we have info about startBluetoothSco(), stopBluetoothSco() and setSpeakerphoneOn(boolean) deprecation. I'm using all three methods and now on Android 12 I'm iterating through getAvailableCommunicationDevices(), comparing type of every item and if desired type found I'm calling setCommunicationDevice(targetAudioDeviceInfo). I'm NOT switching audio mode at all now, staying on MODE_NORMAL. All my streams are AudioManager.STREAM_VOICE_CALL type (where applicable)

for built-in earpiece audio playback aka. "ear-friendly mode" we were using

In golang I have taken an array ARR1 which represents a time series ( could be audio or in my case an image ) where each element of this time domain array is a floating point value which represents the height of the raw audio curve as it wobbles ... I then fed this floating point array into a FFT call which returned a new array ARR2 by definition in the frequency domain where each element of this array is a single complex number where both the real and the imaginary parts are floating points ... when I then fed this array into an inverse FFT call ( IFFT ) it gave back a floating point array ARR3 in the time domain ... to a first approximation ARR3 matched ARR1 ... needless to say if I then took ARR3 and fed it into a FFT call its output ARR4 would match ARR2 ... essentially you have this time_domain_array --> FFT call -> frequency_domain_array --> InverseFFT call -> time_domain_array ... rinse N repeat

I know Web Audio API has a FFT call ... do not know whether it has an IFFT api call however if no IFFT ( inverse FFT ) you can write your own such function here is how ... iterate across ARR2 and for each element calculate the magnitude of this frequency ( each element of ARR2 represents one frequency and in the literature you will see ARR2 referred to as the frequency bins which simply means each element of the array holds one complex number and as you iterate across the array each successive element represents a distinct frequency starting from element 0 to store frequency 0 and each subsequent array element will represent a frequency defined by adding incr_freq to the frequency of the prior array element )

Each index of ARR2 represents a frequency where element 0 is the DC bias which is the zero offset bias of your input ARR1 curve if its centered about the zero crossing point this value is zero normally element 0 can be ignored ... the difference in frequency between each element of ARR2 is a constant frequency increment which can be calculated using

You have to update tools for AVD in the IDE. Android Emulator is 31.2.6

It seems to have been removed in version 9, but the documentation has not been updated. You can use openRecorder() instead or switch to an older version of the library.

Searching for this seems to suggest this used to be possible but was famously broken, because the event wouldn't fire, or would fire only once.

The client.voiceStateUpdate event used to give you a VoiceState that had a speaking property, which would tell you if someone was speaking (which seems like it never really worked).

The current discord.js documentation for VoiceState shows this property no longer exists, and you cannot do what you're asking using discord.js alone.

Edit: as per MrMythical's comment below, discord.js/voice has voiceRecievers, which exposes voiceReciever.speakingMap.users, a map of users currently speaking. you may get events for it by registering a listener.

client.voice.adapters maps guild ids to voice adapters. It returns a Map and Maps have a size property that returns the number of elements in that Map.

Would this work?

OK, I found out what was wrong. I was using Microsoft Edge and it seems that Edge only shows some of Microsoft voices. If I use Firefox, the other installed voices will also show up. So it was Edge's fault.
