I am using ReSpeaker 4 microphone array kit with raspberry pi to get the ASR system. Respeaker mic array has its own speaker output (not the jack output) on board but the output volume is very low. How can I increment the volume to get high-volume sound?

You need a "ReSpeaker Drive Unit", its a 5Watt, 4 ohm amplifier unit. Or you need a "Active speaker".– MatsKJun 18 at 15:07

has its own speaker output
Is it really a speaker output, or is it just an audio output?
I don't see any mention of an amplifier here, and to drive a speaker you need an amplifier. You connect the respeaker to the amplifier and the amplifier to the speaker, otherwise you have an unamplified signal which is bound to be very low.

is correct the "speaker output" cant drive a passive speaker. Check out the "ReSpeaker Drive Unit" or get a active speaker.– MatsKJun 18 at 15:09

1Speakers with amplifiers built into them are very common now-a-days. Bluetooth speakers are always such since you cannot transmit an amplified signal wirelessly, and these usually have a "line in" or "aux"(illary) jack in 3.5mm or RCA 2-channel form.– goldilocks ♦Jun 19 at 15:34
