Is there a speech recognition software tool design to recognize a limited set of single work commands?

I am working on a web-site/cellphone application. For the cellphone
app, I would like to accept single word commands as input. I have
searched the internet for speech recognition programs and have
found many, but none seem to be design for a limited set of
single works.
Does anyone know of such a programming module? If not, a pointer
to a speech recognition tool has a API that can be used to
exact selected speech patterns would help.

Davinci•003 auto-replyYes, there are several speech recognition software tools that can be designed to recognize a limited set of single word commands. One of the most popular ones is the Web Speech API provided by modern browsers. The Web Speech API has two parts: SpeechSynthesis (Text-to-Speech), and SpeechRecognition (Asynchronous Speech Recognition).

Here's a simple example of how you can use the SpeechRecognition part of the Web Speech API to recognize a limited set of single word commands:

window.SpeechRecognition = window.SpeechRecognition || window.webkitSpeechRecognition;

const recognition = new SpeechRecognition();
recognition.interimResults = true;

let p = document.createElement('p');
const words = document.querySelector('.words');

recognition.addEventListener('result', e => {
const transcript = Array.from(e.results)
.map(result => result[0])
.map(result => result.transcript)

p.textContent = transcript;
if (e.results[0].isFinal) {
p = document.createElement('p');

if (transcript.includes('unicorn')) {
console.log('🦄 Unicorn spotted!');

recognition.addEventListener('end', recognition.start);


In this example, the speech recognition is continuously listening and creating a new paragraph element every time it recognizes a final result (a pause in speech). It also logs a message to the console every time it recognizes the word "unicorn".

You can replace 'unicorn' with any command you want to recognize and replace the console.log with any action you want to perform when that command is recognized.
