The future perfect continuous depicts past/present/future actions that continue up until a certain point. Like the future perfect and future continuous, it’s used with a specified time.

[will] + [be] + verb [present participle ] + ing

Use the future continuous tense for future actions happening over a period of time, especially when a specific time is mentioned. The future continuous tense also shows more certainty and likelihood than the simple future.

By this time tomorrow, I will be drinking margaritas on the beach.

We will be attending a meeting from noon until 3 p.m.

Future (simple)

Use the simple future for actions that have not happened yet but will later. To form the simple future, just place the modal verb will before the root form of the main verb. (Note that if the action will happen in the near future, you can use the present continuous instead.)

She will be president one day.

I will not go to the wedding without a date!

Past (Perfect Continuous)

[had] + [been] + [present participle]

The past perfect continuous tense is used just like the past (perfect), except it describes ongoing actions that happened in the past instead of a one-time occurence. It’s often used with the words when, until, and before to connect it to another past action.

The past perfect continuous is a verb tense that indicates something that

began in the past, continued in the past, and also ended at a defined point in the past

note:

The past perfect tense uses the past participle—in this case, been—with the word had. Unlike the present perfect tense, the word had is used regardless of what the subject is.

For example, had been is correct in both of these sentences despite the fact that one sentence has a singular subject and the other has a plural subject:

The cat had been quiet all morning.
The cats had been quiet all morning.

It is combined with the present participle of verbs to form the past perfect continuous tense. For example:

By the time I arrived, they had been [waiting for hours] (present particple of verb ‘wait’).

Other Examples

[He had been drinking milk out the carton] when [Mom walked into the kitchen].

Both
His milk drinking began in the past, continued in the past, and ended at a defined point in the past when his Mom walked into the kitchen.

I [had] [been] [working at the company] for five years when I got the promotion.

He began workking at the compnay, continued in the past, and ended that line of work when he got the promotion.

He began as a proofreader, continued in the past, and ended at a defined point in the past when he got his job as a writer.

I [had] [been] [living on my friend’s couch] for a year until they kicked me out.

The person began living at his friend’s couch, continued in the past, and ended in the past, when they kicked him out.

We [had] [been] [trying to open the door] for five minutes when Jane found her key

We tried opening the door in the past, continued in the past, and ended in the past when Jane found her keys.

The Difference Between Past Tense and Past Participle

May 1, 2023May 1, 2023Posted in My Past

So, what’s the difference between the past tense and the past participle?

Basically, the past tense is a tense while the past participle is a specific verb form used in the past and present perfect tenses.

The past participle is not a tense. It’s a form of a verb and can’t be used on its own. You need an auxiliary verb, such as “have” or “had.” Because of this, the past participle is commonly used as a compound verb.

Let’s take a look at two words in the past tense and then the past participle.

Past tense:

I lived in the United States for seven years.
I listened to this song five times.
We talked about this book.
I ate breakfast at 10 o’clock yesterday.
Past participle:

I had lived in the United States for seven years.
I have listened to this song five times.
The book has been talked about.
I had eaten breakfast by 10 o’clock yesterday.

html5 audio recorder

html5-audio-recorder

HTML

First we have the controls. We have a button to record, and stop the recording.

  <button id="recordButton">Record</button>
  <button id="stopButton">Stop</button>

1 2	<button id="recordButton">Record</button> <button id="stopButton">Stop</button>

Then we have a recordingsList list tag to hold all the recordings.

  <p><strong>Recordings:</strong></p>
  <ol id="recordingsList"></ol>

1 2	<p><strong>Recordings:</strong></p> <ol id="recordingsList"></ol>

Recorder.js

We create a new AudioContext, which we use it as a parameter in Recorder class.
We must implement the onAnalysed callback handler.

const audioContext =  new (window.AudioContext || window.webkitAudioContext)();
 
const recorder = new Recorder(audioContext, {
  // An array of 255 Numbers
  // You can use this to visualize the audio stream
  // If you use react, check out react-wave-stream
  onAnalysed: data => {
    
    // console.log(data)
  }
}); 
 
let isRecording = false;
let myBlob = null;
 
navigator.mediaDevices.getUserMedia({audio: true})
  .then(stream => recorder.init(stream))
  .catch(err => console.log('Uh oh... unable to get stream...', err));

const audioContext = new (window.AudioContext || window.webkitAudioContext)();

const recorder = new Recorder(audioContext, {

// An array of 255 Numbers

// You can use this to visualize the audio stream

// If you use react, check out react-wave-stream

onAnalysed: data => {

// console.log(data)

}

});

let isRecording = false;

let myBlob = null;

navigator.mediaDevices.getUserMedia({audio: true})

.then(stream => recorder.init(stream))

.catch(err => console.log('Uh oh... unable to get stream...', err));

Only then we can start to use the recorder

start record handler

function startRecording() {
  recorder.start()
    .then(() => isRecording = true);
}

function startRecording() {

recorder.start()

.then(() => isRecording = true);

}

stop record handler

function stopRecording() {
  recorder.stop()
    .then(({blob, buffer}) => {
      myBlob = blob;
 
      var recordingsList = document.getElementById("recordingsList");
      var url = URL.createObjectURL(myBlob);
        var au = document.createElement('audio');
        au.controls = true;
        au.src = url;
        var li = document.createElement('li'); // create the list item
        li.appendChild(au); //add the new audio element to li
        li.appendChild(document.createTextNode(" "))//add a space in between
    
        //add the li element to the ol
        recordingsList.appendChild(li);

    });
}

function stopRecording() {

recorder.stop()

.then(({blob, buffer}) => {

myBlob = blob;

var recordingsList = document.getElementById("recordingsList");

var url = URL.createObjectURL(myBlob);

var au = document.createElement('audio');

au.controls = true;

au.src = url;

var li = document.createElement('li'); // create the list item

li.appendChild(au); //add the new audio element to li

li.appendChild(document.createTextNode(" "))//add a space in between

//add the li element to the ol

recordingsList.appendChild(li);

});

}

Assign handlers to event listeners.

var recordButton = document.getElementById("recordButton");
var stopButton = document.getElementById("stopButton");
recordButton.addEventListener("click", startRecording);
stopButton.addEventListener("click", stopRecording);

var recordButton = document.getElementById("recordButton");

var stopButton = document.getElementById("stopButton");

recordButton.addEventListener("click", startRecording);

stopButton.addEventListener("click", stopRecording);

Audio Recorder used here works for almost all browsers if we run it as html5 web page.
For verification, it has been tested on:

– Apple 7 (Joy’s) Apple 14 (Ray’s)
– Wechat browser
– Chrome
– Safari
– Huawei browsers (latest updates)
– QQ browser

Sample demos on device

apple7-recorder

huawei-recorder

Solution

1) We remove all recording audios from the client app.

2) Instead, we’ll have a homework link, which opens the html5 web page (external).
In that html5 web page, we’ll list the homework words and sentences, then have them record it.

Pronoun

March 28, 2023March 28, 2023Posted in My Past

A pronoun is a word that stands in for a noun, often to avoid the need to repeat the same noun over and over.

For example, the usage ‘he’, so you don’t need to repeat Thor over and over and over.

Like nouns, pronouns can refer to people, things, concepts, and places. Most sentences contain at least one noun or pronoun.

Often used before another noun. “He,” “she,” and “it” are third person pronouns.

People tend to use “pronouns” to mean personal pronouns specifically, but there are many other kinds of pronouns that are just as important to English grammar. The words highlighted in bold below are all pronouns.

Examples: Pronouns

I asked her if the headphones were hers, but she said they belonged to someone else.

It might rain tomorrow, but there isn’t much we can do about that.

These are the days that I like best.

Which of them do you prefer? Help yourself to whichever you like.
