                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
                intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say something");
                try {
                    startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
                } catch (ActivityNotFoundException a) {
                    Toast.makeText(getApplicationContext(), "Sorry! Your device doesn\\'t support speech input",
                            Toast.LENGTH_SHORT).show();
                }
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case REQ_CODE_SPEECH_INPUT: {
                if (resultCode == RESULT_OK && null != data) {

                    ArrayList<String> result = data
                            .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                    String speechText = speechinput.getText().toString() + "\n" + result.get(0);
                    speechinput.setText(speechText);
                }
                break;
            }
        }
    }
}

•  Now Open res -> layout -> activity_main.xml and then add following code :

XML (activity_main.xml)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >


    <TextView
        android:id="@+id/speechinput"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="100dp"
        android:textColor="#008000"
        android:textSize="26dp"
        android:textStyle="normal" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="60dp"
        android:gravity="center"
        android:orientation="vertical">

        <ImageButton
            android:id="@+id/imagebt"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@null"
            android:src="@drawable/speaker" />


        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:text="Press the Mic to Speak"
            android:textColor="#7FFFFF"
            android:textSize="15dp"
            android:textStyle="normal" />
    </LinearLayout>
