+#  By the default, it needs to wait at least 30 seconds
 whispering --language en --model tiny
 ```
 
 - ``--help`` shows full options
-- ``--model`` set the [model name](https://github.com/openai/whisper#available-models-and-languages) to use. Larger models will be more accurate, but may not be able to transcribe in real time.
+- ``--model`` sets the [model name](https://github.com/openai/whisper#available-models-and-languages) to use. Larger models will be more accurate, but may not be able to transcribe in real time.
 - ``--language`` sets the language to transcribe. The list of languages are shown with ``whispering -h``
 - ``--no-progress`` disables the progress message
 - ``-t`` sets temperatures to decode. You can set several like ``-t 0.0 -t 0.1 -t 0.5``, but too many temperatures exhaust decoding time
 - ``--debug`` outputs logs for debug
-- ``--no-vad`` disables VAD (Voice Activity Detection). This forces whisper to analyze non-voice activity sound period
+- ``--vad`` sets VAD (Voice Activity Detection) threshold. The default is ``0.5``. ``0`` disables VAD and forces whisper to analyze non-voice activity sound period. Try ``--vad 0`` if VAD prevents transcription.
 - ``--output`` sets output file (Default: Standard output)
+- ``--frame``: the number of minimum frames of mel spectrogram input for Whisper (default: ``3000``. i.e. 30 seconds)
 
 ### Parse interval
 
-Without ``--allow-padding``, whispering just performs VAD for the period,
-and when it is predicted as "silence", it will not be passed to whisper.
-If you want to change the VAD interval, change ``-n``.
+By default, whispering performs VAD for every 3.75 second.
+This interval is determined by the value of ``-n`` and its default is ``20``.
+When an interval is predicted as "silence", it will not be passed to whisper.
+If you want to disable VAD, please make VAD threshold 0 by adding ``--vad 0``.
 
-If you want quick response, set small ``-n`` and add ``--allow-padding``.
-However, this may sacrifice the accuracy.
-
-```bash
-whispering --language en --model tiny -n 20 --allow-padding
-```
+By default, whispering does not perform analysis until the total length of the segments determined by VAD to have speech exceeds 30 seconds.
+This is because the original Whisper assumes that the inputs are 30 seconds segments.
+However, if silence segments appear 16 times (the default value of ``--max_nospeech_skip``) after speech is detected, the analysis is performed.
+You can make the length of segments smaller with ``--frame`` option (default: 3000), but it sacrifices accuracy because this is not expected input for Whisper.

-## Tips
+## For Developers
 
-## PortAudio Error
+1. Install [Python](https://www.python.org/) and [Node.js](https://nodejs.org/)
+2. [Install poetry](https://python-poetry.org/docs/) to use ``poetry`` command
+3. Clone and install libraries
 
-If you get ``OSError: PortAudio library not found``: Install ``portaudio``
+    ```console
+    # Clone
+    git clone https://github.com/shirayu/whispering.git
 
-```bash
-# Ubuntu
-sudo apt-get install portaudio19-dev
-```
+    # With poetry
+    poetry config virtualenvs.in-project true
+    poetry install --all-extras
+    poetry run pip install -U torch torchaudio --extra-index-url https://download.pytorch.org/whl/cu116
+
+    # With npm
+    npm install
+    ```
+
+4. Run test and check that no errors occur
+
+    ```bash
+    poetry run make -j4
+    ```
+
+5. Make fancy updates
+6. Make style
+
+    ```bash
+    poetry run make style
+    ```
+
+7. Run test again and check that no errors occur
+
+    ```bash
+    poetry run make -j4
+    ```
+
+8. Check typos by using [typos](https://github.com/crate-ci/typos). Just run ``typos`` command in the root directory.
+
+    ```bash
+    typos
+    ```
+
+9. Send Pull requests!
