Automatically transcribe your Evernote voice notes

I am a big believer in taking notes and working on my personal infrastructure. I find joy in polishing the “Artur OS” and removing little pockets of friction in my setup. Have a look at my automation philosophy:

Recently, we adopted a dog and I have quite a bit of time spent walking. What if I could use it for some deep thinking?

So I wrote a bot.

How does it work?

A: I record an audio note on my phone:

B: I run my magical code

C: A transcription shows underneath

D: Profit!

There are other ways to solve this problem. Particularly, Otter.AI is a great service to transcribe your notes. However, it requires extra manual steps to open the app, export recordings, etc.

If you don’t have an elaborate setup behind your Evernote account, I recommend you check out Otter.

What do you need:

  1. You need to set up the PHP (Yes) SDK for Evernote
  2. You need an API key to Google Cloud Speech API. You don’t need a client library! Just follow these steps:
    1. Enable the API for your project here
    2. Create a new “API Interface Key” here

This code assumes you already search for a note and pass it in. I tag a note with `Tools`. A cron job periodically checks the label and does certain magical things on the notes tagged with it.


It finds the audio recording in your Evernote note and transcribes it:

function transcribe_audio_file_in_a_note( $evernoteClient, $note ) {
// This will find the place where file is embedded, so we can display the transcription underneath.
if( preg_match( '#<en-media hash="([a-z0-9]+)"[^>]+>#is', $note->content, $res ) ) {
$id = hex2bin($res[1] );
$resources = array_filter( $note->resources, function( $resource ) use ( $id ) {
return $resource->data->bodyHash === $id;
} );
if( $resources ) {
$resource = array_shift( $resources );
if ( isset( $resource->mime ) && $resource->mime === 'audio/x-m4a' ) {
// Only audio files
if ( isset( $resource->attributes->applicationData->keysOnly['transcribed'] ) ) {
$this->log( LOG_INFO, 'This resource is already transcribed.' );
// Set for the future
$evernoteClient->client->getNoteStore()->setResourceApplicationDataEntry( $resource->guid, 'transcribed', 'true' );
// this is your Google Speech API token
$token = "tsrtrastr8astars8tras8t";
$in = tempnam(sys_get_temp_dir(), 'evernote_transcript') . '.mp4';
$out = tempnam(sys_get_temp_dir(), 'evernote_transcript') . '.wav';
$data = $evernoteClient->client->getNoteStore()->getResourceData( $resource->guid );
file_put_contents( $in, $data );
// Because Google Speech API is crap and cannot deal with other formats, we have to recode it.
system( "ffmpeg -i $in $out" );
$data = file_get_contents( $out );
$payload = array(
"audio" => array( "content" => base64_encode( $data ) ),
"config" => array(
"languageCode" => "en-US",
"alternativeLanguageCodes" => [ "pl-PL" ], // I only use English or Polish. Your mileage may vary.
"encoding" => "LINEAR16",
"sampleRateHertz" => 44100,
"maxAlternatives" => 1,
"enableAutomaticPunctuation" => true
$payload = json_encode( $payload );
$context = stream_context_create( array(
'http' => array(
'ignore_errors' => true,
'header' => "Content-Type: application/json\r\n",
'method' => 'POST',
'content' => $payload
) );
// Wondering about the v1p1beta1 here? You have to use this version to have alternativeLanguageCodes. This of course is not in documentation.
$result = file_get_contents( "$token&quot;, false, $context );
$result = json_decode( $result, true );
if ( ! isset ( $result['results'][0]['alternatives'][0]['transcript'] ) ) {
$this->log( LOG_WARNING, 'Empty transcript. ' . print_r( $result, true ) );
$text = $result['results'][0]['alternatives'][0]['transcript'];
$this->log( LOG_INFO, 'Transcript OK: ' . $text );
$new_body = str_replace( $res[0], $res[0] . "<div style='font-style: italic'>$text</div>",$note->content );
$note->content = $new_body;
$evernoteClient->client->getNoteStore()->updateNote( $note );
return $note->content;

More of my adventures in automation:

Alfred Evernote Snippets

This is sort of a plugin to a great OSX app, Alfred. It adds all notes in Evernote “Snippets” Notebook as a quick-paste snippet in Alfred.

I use both alfred and evernote extensively, so Im quite happy about this one!


  1. Provided you have Evernote, Alfred and powerpack and this workflow installed
  2. Put some snippets in “Snippets” notebook in evernote
  3. Hit afred `s your_note_title`
  4. enter
  5. note content is now pasted to your focused window

Making of:

Script filter:
var q = "{query}";
var values = Application('Evernote').findNotes("notebook:Snippets " + q);
var ret = '<?xml version="1.0"?><items>';
for (var i=0; i<values.length; i++ ) {
var title = values[i].title();
var val = values[i].htmlContent().replace(/<br\/>/g,'{enter}').replace(/<[^>]*?>/g,"");
var sub = values[i].htmlContent().replace(/\n/g,'').replace(/<[^>]*?>/g,"");
ret += '<item arg="'+val+'"><title>' + title + '</title><subtitle>' + sub + '</subtitle></item>';
ret += "</items>";
You will need this to properly handle spaces (script filter has trouble with that)
NSAScript (synchronous)
on replace_chars(this_text, search_string, replacement_string)
set AppleScript's text item delimiters to the search_string
set the item_list to every text item of this_text
set AppleScript's text item delimiters to the replacement_string
set this_text to the item_list as string
set AppleScript's text item delimiters to ""
return this_text
end replace_chars
on alfred_script(q)
return replace_chars(q, "{enter} ", "\n")
end alfred_script

Evernote: Using Online Notes for Performing Qualitative Research

In June issue of Qualitative Sociology Review (Issue here) you can find mine and Krzysztof Stachura’s paper about using Evernote platform in the course of academic research. Please, keep in mind that paper is in Polish.


The paper is a presentation of potential ways to use Evernote as a simple and cheap alternative to professional CAQDA (Computer-Assisted Qualitative Data Analysis) software packages, along with pointing specific limitations of the tool.
The main functions useful in research and for analytic purposes are depicted, as well as techniques that enable the application of grounded theory methodology using Evernote are. Moreover, similarities and differences between Evernote and NVivo 10 are presented, and the analytical perspectives for the near future concerning the evolution of Evernote are drawn.
