How to convert any mp3 file to .wav 16khz mono 16bit

Please, help to choose solution for converting any mp3 file to special .wav - I'm a newbie with Linux command line tools, so It's hard for me right now.

I need to get wav with 16khz mono 16bit sound properties from any mp3 file. I was trying

ffmpeg -i 111.mp3 -ab 16k out.wav,

but I got wav with the same rate as mp3 (22k).

Please, help to construct right command line

Use this example:

import os 
from pydub import AudioSegment
import numpy as np 
from tqdm import tqdm 

for src in tqdm (mp3_files):
    
    des = src.replace('.mp3','.wav')
    try:
        sound = AudioSegment.from_mp3(src)
        sound.set_channels(1)
        sound = sound.set_frame_rate(16000)                
        sound = sound.set_channels(1)    
        sound.export(des, format="wav")

    except:
        print(src)
        continue

kdazzle's solution is almost there - it still output a stereo wav, here is a slightly modified version that generate mono:

ffmpeg -i 111.mp3 -acodec pcm_s16le -ac 1 -ar 16000 out.wav

also, if this is for pre-processing speech data for sphinx 4 see here: Convert audio files for CMU Sphinx 4 input
