As the redirection will be\ninternal only, the current model identifiers and code will remain valid and\ncontinue to serve traffic.\n\nThe affected language tags are: `en-au`, `en-gb`, `de`, `de-de`, `es`, `es-es`,\n`es-us`, `fr`, `fr-ca`, `fr-fr`, `it`, `it-it`, `ja`, `pt-br`.\n\nThe following table shows the routing of Speech-to-Text\n`phone_call` model that will take place when the migration takes effect. If your\nconfiguration matches the language tag and the first three columns in the table,\nthe new model identifier is listed in the fourth column.\n\nMigration options\n-----------------\n\nThere are three migration options: early opt-in, automatic, and temporary\nopt-out.\n\n### Opt in and migrate earlier\n\nTo opt in proactively, change the speech model identifier that you have been\nusing in the [Conversational Agents (Dialogflow CX)\nAPI](/dialogflow/cx/docs/reference/rest/v3/ConversationTurn#inputaudioconfig)\nand [Dialogflow ES\nAPI](/dialogflow/es/docs/reference/rpc/google.cloud.dialogflow.v2#inputaudioconfig)\nwith the updated one. For Conversational Agents (Dialogflow CX), you can also change the [model\nidentifier](/dialogflow/cx/docs/concept/agent#stt-model-selection) in the\n**Advanced speech settings** under **Speech and IVR settings** in the\nConversational Agents (Dialogflow CX) console.\n\nMigrating your project proactively gives you time to test the models and take\nadvantage of the improved accuracy and robustness earlier.\n\nIf you experience issues with the new models, [open a Google Cloud support\ncase](/support/docs/customer-care-procedures) with issue details.\n\n### Migrate automatically\n\n| **Note:** See [migration status](#status).\n\nTo be migrated automatically, no action is required on your part. The existing\nSpeech-to-Text model identifiers are valid and we will shift traffic\ninternally.\n\n### Opt out and migrate later\n\nDue to the suspended [migration status](#status), new opt-out requests are not\naccepted. If your projects were opted out before July 2024, they will remain in\nthis state until further announcement."]]
