On the week of October 30, 2023, auto speech adaptation (CX, ES) will be updated for non-English agents. No major behavior changes are expected.

If you notice speech recognition issues in Dialogflow CX, you can mitigate by enabling manual speech adaptation on flows and pages experiencing issues. You can tune the adaptation as follows:

  1. On the problematic flows and pages, disable auto speech adaptation by enabling manual speech adaptation without adding phrases.

  2. If your agent is unable to recognize certain words and phrases, add those phrases to the adaptation with no boost.

  3. If your agent is still unable to recognize certain words and phrases after step 2, duplicate those phrases so that you have one without boost and one with boost.

If you notice speech recognition issues in Dialogflow ES, you can mitigate by using the speechContexts field at runtime which overrides auto speech adaptation or by updating your agent design.

  2. To get the source field value, use the originalDetectIntentRequest.source field from the Dialogflow WebhookRequest message.
  3. To send rich response messages from your webhook to the Facebook Messenger integration, use the WebhookResponse.fulfillment_messages[].payload field.

If you have any questions, reach out to your primary support channel.

We are extending the V1 API shutdown deadline to March 31st, 2020 May 31st, 2020. Migrate to the V2 API as described here.

If you use Dialogflow exclusively for Actions on Google, you don't need to migrate your agent to the V2 API. However, note the following changes:

  • The Dialogflow simulator will show responses in the V2 format and the "Copy curl" button will generate requests in the V2 format. This should have no impact on the functionality of the Actions on Google simulator.
  • You will no longer be able to call API methods for the V1 intents and entities resources. You will still be able to modify your agent using the Dialogflow Console.

October 17, 2019

When calling the API to provide an intent priority value, the behavior has changed to the following:

  • If the supplied value is unspecified or 0, the service translates the value to 500,000, which corresponds to the Normal priority in the console.
  • If the supplied value is negative, the intent is ignored in runtime detect intent requests.

Prior to this change, a value of 0 was stored as-is by the service. Any agents created before this change may still have intent priority values of 0. For runtime detect intent requests, a value of 0 is treated as -1, and the intent is ignored.

October 01, 2019
