+Azure Ai Transcribing
+=====================
+
+This project is meant to demonstrate and document my attempts to create a video transcribe service
+using Azure AI.
+
+## Creating Azure Ai Resource
+- I created just plain *Azure AI Services* resource from Azure Portal
+- I chose Sweden Central as location and standard S0 as pricing tier
+- I am using Visual Studio license attached Azure account so I have roughly 150€ of free credits
+- here's how the portal looked after 
+
+![Azure AI resource](note-resources/azure-ai-resources-list-after-creation.png)
+
+- all audio files need to be in specific format, I am using ffmpeg to convert
+
+```shell
+ffmpeg -i [INPUT].mp3 -acodec pcm_s16le -ac 1 -ar 16000 [OUTPUT].wav
+```
+
+## Running this app
+
+- first get your Key and Region data from Azure Portal
+- then set environment variables
+
+```shell
+    export SPEECH_KEY=your_key
+    export SPEECH_REGION=your_region 
+    
+    dotnet run
+```
+
+## Using this app
+- You need to fill out the `Data` folder with some .wav files
+- The app will then display those files and you can choose which to transcribe
+- The app will then display the transcription
+
+### Experimentation results & thoughts
+- I used three different files of varying lengths to try to transcribe each
+- It seems there is a limit as to how long the audio file can be
+- It might be that the silence detection is too strict
+  - Yeah documentation says as much
+> This example uses the RecognizeOnceAsync operation to transcribe utterances of up to 30 seconds, or until silence is detected.
+- The results that I do get are very readable
+-
