How-to: Download, Compile & Run C++ Samples
Please follow our guide How-to: Install & Configure Conan.
This is our build system, version
3.16 or higher is needed. You can either get it via your Linux package manager or the official installer (don’t forget to add the binary to PATH if needed!)
Samples are available through Conan. Here is the list of available samples:
Demonstrate the use of Speech Synthesis right after Voice Recognition.
Demonstrate the use of dynamic models (i.e. using slots inside grammars and filling them at runtime).
Demonstrate how to do a gap-less Voice Recognition between a Wake-up Word and another model.
Demonstrate how to use Speech Synthesis.
Demonstrate how to use Voice Biometrics.
Demonstrate how to use the Natural Language Understanding technology alongside voice recognition
Sample availability depends on your contract. To determine if you have access to it, do this:
conan search -r vivoka-customer <sample-name>
A list of package reference will appear if you have access, always select the latest version.
First you’ll have to check the required options:
conan inspect -r vivoka-customer -a options <sample-name>/<version>@vivoka/customer
Select the engines you want (you need to have access to them too, check your contract!) like so:
cd vdk-samples # Example using the CSDK TTS engine conan install -if <sample-name> <sample-name>/<version>@vivoka/customer -o tts_engine=csdk
If the download fails with an error saying a package cannot be found, it means you don’t have access to the related engine(s). If you are sure your contract includes this technology provider nonetheless, please open a support ticket and we will correct that as soon as possible.
Each sample features a
README.md file that explains how to build it along with its options. But generally speaking, there are two big steps:
# Check the options conan inspect . -a options # First install the dependencies and configure options for this build (do it once) conan install . -if build -o opt1=value1 -o opt2=value2 # Build the program conan build . -if build
To check the possible options and their values, run the command . Most sample will require you to select a provider for the engines you want to use.
Running the sample
cmd /c "build\generators\conanrun.bat && build\Release\<executable>.exe"
//c if writing this command from Git Bash!
conanrun.bat script is only needed when starting the program from the build tree, its purpose is to add the dependencies' DLL to the PATH before attempting to run the program.
When deploying your executable to a device, bring all the required DLLs next to the executable.
Conan can’t build the SDK but my profile is correct, why?
Dependencies whose name ends with
@vivoka/customer cannot be built on your machine as we only give you the resulting libraries or executables. If Conan tries to build one of our packages, it means there is a configuration mismatch that needs to be corrected. Please check that:
Your profile is in Release mode (e.g.
conan profile get settings.build_type <profile_name>returns
You have run the command to enable the revision mode (see the Conan setup guide)
Conan can’t install asound library
