Tinkoff VoiceKit SMS Verification

Developers testing speech recognition and text-to-speech can clear the Tinkoff VoiceKit SMS verification with a virtual number and keep the account off a personal line.

Tinkoff VoiceKit is the speech recognition and speech synthesis service that Russia's Tinkoff Bank, renamed T-Bank on 5 June 2024, offers to developers. You connect to its gRPC API with an API key and a secret key, and sample code is published for Python, Node.js, Go, Java, C# and Ruby. Phone verification helps confirm who owns a cloud account and keeps abuse down.

You enter a virtual number during registration and confirm the code. That can suit engineering teams comparing speech recognition and synthesis options, developers prototyping call-centre or voice-assistant features, and anyone keeping test accounts apart from a personal number. Note that speech synthesis may need to be enabled separately for your API key.

T-Bank came under European Union and US sanctions in 2023, so check the sanctions rules that apply to you and your company before using or paying for the service from outside Russia. Keep API keys out of your source code by storing them in environment variables, and decide in advance where personal data in audio recordings will be processed.
