+1. **New Knowledge Base API Endpoints**: You can now create a knowledge base with [`POST /knowledge-base`](https://api.vapi.ai/api#/Knowledge%20Base/KnowledgeBaseController_create), list knowledge bases with [`GET /knowledge-base`](https://api.vapi.ai/api#/Knowledge%20Base/KnowledgeBaseController_findAll) or [`GET /knowledge-base/{id}`](https://api.vapi.ai/api#/Knowledge%20Base/KnowledgeBaseController_findOne) for a specific knowledge base, update a knowledge base with [`PATCH /knowledge-base/{id}`](https://api.vapi.ai/api#/Knowledge%20Base/KnowledgeBaseController_update), or delete a knowledge base with [`DELETE /knowledge-base/{id}`](https://api.vapi.ai/api#/Knowledge%20Base/KnowledgeBaseController_remove). Refer to the [Vapi API endpoints](https://api.vapi.ai/api#/) for more details.
+
+
+
+
+
+
+2. **Configure Custom Knowledge Bases for your Assistant**: Configure a custom knowledge base for your assistant in three steps by first uploading a file [through the dashboard](https://dashboard.vapi.ai/files) or [the API](https://api.vapi.ai/api#/Files/FileController_create), then [create a knowledge base](https://docs.vapi.ai/knowledgebase#step-2-create-a-knowledge-base), and lastly [updating your assistant](https://docs.vapi.ai/knowledgebase#step-3-create-an-assistant) with the knowledge base id. You can also assign a knowledge base to models like `GroqModel`, `VapiModel`, `GoogleModel`, and others using the new `knowledgeBaseId` property.
+
+
+3. **Integration with Trieve Knowledge Base**: Vapi now supports [Trieve](https://trieve.ai/) as our first knowledge base provider. Refer to [our docs](https://docs.vapi.ai/knowledgebase#step-2-create-a-knowledge-base) for an example of how to use Trieve.
+
+
+4. **Inflection AI Credential Management**: You can now manage Inflection AI credentials through the [updated providers credentials](https://dashboard.vapi.ai/keys) page. `Call.endedReason` also now enumerates new values like `'pipeline-error-inflection-ai-llm-failed'` to indicate specific Inflection AI errors.
+
+
+
+
+
+
+5. **New Transfer Mode with Summary in SIP Header**: You can now configure `TransferPlan.mode` to `'blind-transfer-add-summary-to-sip-header'` to forward calls and include a summary in the SIP header called `X-Transfer-Summary`. You can also add custom SIP headers during a transfer call using the `sipHeaders` property in `TransferDestinationSip`.
+
+
+6. **Azure Credential Service Default**: When creating or updating Azure credentials in the [updated providers credentials](https://dashboard.vapi.ai/keys), the `service` field now defaults to `'speech'`.
+
+
+7. **Support for Cantonese in Deepgram Transcriber**: The `DeepgramTranscriber.language` option now includes `'zh-HK'` for Cantonese (Hong Kong).

+title: Voice Fallback Plan
+subtitle: Configure fallback voices that activate automatically if your primary voice fails.
+slug: voice-fallback-plan
+---
+
+
+ Voice fallback plans can currently only be configured through the API. We are working on making this available through our dashboard.
+
+
+## Introduction
+
+By default, if an assistant's primary voice experiences any failure, Vapi will automatically attempt to use other available voices to continue the call. While this ensures call continuity, you might want more control over which specific voices are used as fallbacks.
+
+Fallback plans give you precise control over the fallback sequence. Your assistant will sequentially fallback to only the voices you configure within your plan, in the exact order you specify.
+
+## How It Works
+
+When a voice failure occurs, Vapi will:
+1. Detect the failure of the primary voice
+2. If a custom fallback plan exists:
+ - Switch to the first fallback voice in your plan
+ - Continue through your specified list if subsequent failures occur
+ - Terminate only if all voices in your plan have failed
+3. If no custom fallback plan is configured:
+ - Automatically switch to other available voices
+ - Continue attempting different voices
+ - Terminate only if all available voices have failed
+
+## Configuration
+
+Add the `fallbackPlan` property to your assistant's voice configuration, and specify the fallback voices within the `voices` property.
+- Please note that fallback voices must be valid JSON configurations, and not strings.
+- The order matters. Vapi will choose fallback voices starting from the beginning of the list.
+
+```json
+{
+ "voice": {
+ "provider": "openai",
+ "voiceId": "shimmer",
+ "fallbackPlan": {
+ "voices": [
+ {
+ "provider": "cartesia",
+ "voiceId": "248be419-c632-4f23-adf1-5324ed7dbf1d"
+ },
+ {
+ "provider": "playht",
+ "voiceId": "jennifer"
+ }
+ ]
+ }
+ }
+}
+```
+
+Although **not recommended**, you may choose to disable the default fallback behavior by providing an empty list of voices in your fallback plan:
+
+```json
+{
+ "voice": {
+ "provider": "openai",
+ "voiceId": "shimmer",
+ "fallbackPlan": {
+ "voices": []
+ }
+ }
+}
+```
+
+## Best practices
+
+- Use different providers for your fallback voices to protect against provider-wide outages.
+- Select voices with **similar characteristics** (tone, accent, gender) to maintain consistency in the user experience.
+
+## How will pricing work?
+
+There is no change to the pricing of the voices. Your call will not incur any extra fees while using fallback voices, and you will be able to see the cost for each voice in your end-of-call report.
