used to determine whether the system could recognize voices and perform commands according to the voice given. This test was done by giving voice commands from the same person, other users, different accents, and age ranges.
For program testing, it was carried out to determine whether the program was in accordance with the planned system and whether there was an error. Program testing was related to the programming language and programming software used. Circuit testing was carried out to test whether parts of the circuit, namely inputs such as microphones, processes such as microcontrollers, and outputs (related to actuators) can operate properly or not. The distance test was carried out to test whether the microphone can pick up sound at a specified distance. Meanwhile,
for remote control, distance testing was carried out to test whether the transmitter and receiver can communicate properly. Environmental testing was carried out to measure the noise level whether it affects the system or not. Testing of response time and delay was carried out to test the response of the system when given a voice command, whether the system would immediately execute the command or there was a pause to carry out the command.
Result
The results were obtained from the testing process, in the voice command test, the following results were obtained when voice testing with the same person had high results of more than 80%, while for testing other users had low results of less than 25%, while for testing different accents and age
obtained accents of kelantan, trengganu and kedah are the worst accents and age 60 years and over give a lot of error commands. The results of program testing as a whole did not experience problems, this can be attributed to all research that shows the system could work in accordance with the instructions given. For the results of the circuit testing as a whole there were also no problems, because the circuit could work according to the instructions given, for example in research using the L298N
motor driver, in this study it was known that the motor driver could function properly. The results of the distance test showed that the best distance between the sound source and the microphone was 3 cm - 10 cm, while for remote testing using bluetooth and wi-fi, the best distance was between 1 - 20 m. Apart from distance, the remote control system was also affected by the baud rate and internet speed. The higher the baud rate,
the lower the results, and the higher the internet speed, the higher the results. The results of environmental testing show that a noisy environment would give many errors. This can be seen from an example of a study which states that the room noise level of 34.5 dB gives a success of 86%, while the 62 dB room noise level gives a success of 79%, another example was in another study which states that the best environment for testing was in the library and the worst environment was located at the cafe. In the test results, the response
time and delay were influenced by the distance between the sound
source and the microphone, the farther the distance between the two would make the response of the system longer.
