針對特定的語言代碼和語音設定組合，Conversational Agents (Dialogflow CX) 和含有音訊的 Dialogflow ES 流量將逐步從 command_and_search、default、phone_call 和 video 模型 ID 後方的傳統語音轉文字模型，改為使用新的以 conformer 為基礎的語音模型。由於重新導向只會在內部進行，目前的模型 ID 和程式碼仍會有效，並繼續放送流量。

The\nautomatic migration will remain on hold until further notice (no ETA).\n\nYou can continue to use the classic Speech-to-Text models but are encouraged to\n[opt in](#opt-in) to use conformer-based speech models.\n\nMigration overview\n------------------\n\nFor certain [language tag](/dialogflow/es/docs/reference/language) and speech\nsetting combinations, the Conversational Agents (Dialogflow CX) and Dialogflow ES traffic with audio will\ngradually route away from the classic Speech-to-Text models behind the\n`command_and_search`, `default`, `phone_call`, and `video` model identifiers to\nthe new conformer-based [speech\nmodels](/speech-to-text/docs/transcription-model). As the redirection will be\ninternal only, the current model identifiers and code will remain valid and\ncontinue to serve traffic.\n\nThe tables in the [Migration for `en` and `en-us`language tags](#en-en-us) and\n[Migration for `de`, `en-au`, `en-gb`, `en-in`, `es`, `es-es`, `es-us`, `fr`,\n`fr-ca`, `fr-fr`, `it`, `ja`, `nl`, `pt-br` language\ntags](#non-en-en-us-affected) sections show the routing of Speech-to-Text\nmodels that will take place when the migration takes effect. If your\nconfiguration matches the language tag and the first two columns in the table,\nthe new model identifier is listed in the third column. No change is expected\nfor other configurations.\n\nSee the [Migration options](#options) section to choose the best option for you.\n\nMigration for `en` and `en-us` language tags\n--------------------------------------------\n\nMigration for `de`, `en-au`, `en-gb`, `en-in`, `es`, `es-es`, `es-us`, `fr`, `fr-ca`, `fr-fr`, `it`, `ja`, `nl`, `pt-br` language tags\n--------------------------------------------------------------------------------------------------------------------------------------\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. This approach is\nhighly recommended, especially if you are using a model that will route to the\nnew `telephony` and `telephony_short` models.\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."]]
