Signup or Login to Picovoice Console to get your AccessKey. Make sure to keep your AccessKey secret.

dotnet add package Leopard

Create an instance of the engine:

using Pv;

const string accessKey = "${ACCESS_KEY}";

Leopard leopard = Leopard.Create(accessKey);

Transcribe an audio file by providing an absolute path to the file:

string transcript = leopard.ProcessFile("${AUDIO_FILE_PATH}");

Transcribe raw audio data (sample rate of 16 kHz, 16-bit linearly encoded and 1 channel):

short[] GetAudioData()
{
   // ...
}

string transcript = leopard.Process(GetAudioData());

For the Leopard .NET SDK, we offer demo applications that demonstrate how to use the Speech-to-Text engine on audio files.

git clone --recurse-submodules https://github.com/Picovoice/leopard.git

cd leopard/demo/dotnet/Leopard
dotnet build -c FileDemo.Release

Use the --help flag to see the usage options for the demo:

dotnet run -c FileDemo.Release -- --help

Run the following command to transcribe an audio file:

dotnet run -c FileDemo.Release -- --access_key ${ACCESS_KEY}
                                  --input_audio_path ${AUDIO_PATH}
