Does anyone have an example of how to change the parameters for TTS?  
**The documentation:**  
([class TTS - text to speech — SunFounder Robot HAT documentation](https://docs.sunfounder.com/projects/robot-hat/en/latest/pythonApi/TTS.html))  
**says:**  
_/# amp: amplitude, volume  
/# speed: speaking speed  
/# gap: gap  
/# pitch: pitch  
def espeak\_params(self, amp=None, speed=None, gap=None, pitch=None)_  
   
But doesn’t show how to implement this as a function.  
Can anyone put up an example?

Note the selection of the espeak speech engine.

```auto
from robot_hat import TTS
# https://github.com/sunfounder/robot-hat/blob/main/robot_hat/tts.py

tts = TTS({'engine':'espeak'}) # create a TTS object

# "espeak -h"
# Amp should be in 0 to 200
# gap： unit ms
# speed should be in 80 to 260
# pitch should be in 0 to 99
tts.espeak_params(amp=100, speed=200, gap=5, pitch=50)

tts.say('Hello. Nice to meet you.') # speak word

```
