SpeechToTextV2 class

An interface to Google's Speech-to-Text Api via grpc.

Important! You need an own Google project to use this class.

Constructors

SpeechToTextV2.viaApiKey(String apiKey, String projectId, {String? cloudSpeechEndpoint})

Creates a SpeechToText interface using a API keys.

factory

SpeechToTextV2.viaServiceAccount(ServiceAccount account, {required String projectId, String? cloudSpeechEndpoint})

Creates a SpeechToTextV2 interface using a service account.

factory

SpeechToTextV2.viaThirdPartyAuthenticator(ThirdPartyAuthenticator thirdPartyAuthenticator, {required String projectId, String? cloudSpeechEndpoint})

Creates a SpeechToTextV2 interface using a third party authenticator. Don't worry about updating the access token, the package does it automatically. Example: final SpeechToTextV2 = SpeechToTextV2.viaThirdPartyAuthenticator( ThirdPartyAuthenticator( obtainCredentialsFromThirdParty: () async { // request api to get token final json = await requestCredentialFromMyApi(); return AccessCredentials.fromJson(json); }, ), );

factory

SpeechToTextV2.viaToken(String typeToken, String token, {required String projectId, String? cloudSpeechEndpoint})

Creates a SpeechToTextV2 interface using a token. You are responsible for updating the token when it expires.
