获取和设置离线语音助手模式

读取当前离线语音助手模式，并请求设备能力支持的模式。

前提条件

• 设备已连接，并遵循 OnDeviceVoiceAssistantAPI。
• onDeviceVoiceAssistantCapability 不为 .none。
• 目标模式与报告的能力兼容，且不为 .unknown。

API 参考

框架

AIBuds.xcframework

声明

Swift

Swift

/// The protocol for the on-device voice assistant API.
protocol OnDeviceVoiceAssistantAPI: DeviceAPI {
    /// The current mode of the on-device voice assistant.
    var onDeviceVoiceAssistantMode: OnDeviceVoiceAssistantMode { get }

    /// Sets the mode of the on-device voice assistant.
    /// - Parameters:
    ///   - mode: The desired mode to set.
    ///   - completion: Called when the operation completes.
    ///     - success: `true` when the operation succeeds.
    ///     - error: Error details on failure; otherwise `nil`.
    func setOnDeviceVoiceAssistantMode(_ mode: OnDeviceVoiceAssistantMode,
                                   completion: AIBudsCompletionHandler?)
}

Objective-C

Objective-C

/// The protocol for the on-device voice assistant API.
@protocol AIBudsOnDeviceVoiceAssistantAPI <AIBudsDeviceAPI>
/// The current mode of the on-device voice assistant.
@property(nonatomic, readonly) AIBudsOnDeviceVoiceAssistantMode onDeviceVoiceAssistantMode;

/// Sets the mode of the on-device voice assistant.
/// - Parameters:
///   - mode: The desired mode to set.
///   - completion: Called when the operation completes.
///     - success: `YES` when the operation succeeds.
///     - error: Error details on failure; otherwise `nil`.
- (void)setOnDeviceVoiceAssistantMode:(enum AIBudsOnDeviceVoiceAssistantMode)mode
                           completion:(AIBudsCompletionHandler _Nullable)completion;
@end

请参阅 onDeviceVoiceAssistantMode、setOnDeviceVoiceAssistantMode 和 OnDeviceVoiceAssistantMode。

兼容模式

能力	可展示模式
.none	不显示模式控制
.keywordWakeup	.disabled, .basic
.common	.disabled, .basic, .advanced

使用示例

Swift

Swift

guard let voiceAssistant = device as? OnDeviceVoiceAssistantAPI else {
    print("On-device voice assistant is not supported")
    return
}

print("Current mode: \(voiceAssistant.onDeviceVoiceAssistantMode)")

guard voiceAssistant.onDeviceVoiceAssistantCapability == .common else {
    print("Advanced mode is not supported")
    return
}

voiceAssistant.setOnDeviceVoiceAssistantMode(.advanced) { success, error in
    guard success else {
        print(error?.localizedDescription ?? "Unable to change mode")
        return
    }
    print("Mode changed to advanced")
}

Objective-C

Objective-C

id<AIBudsOnDeviceVoiceAssistantAPI> voiceAssistant =
    (id<AIBudsOnDeviceVoiceAssistantAPI>)self.device;

if (![voiceAssistant conformsToProtocol:@protocol(AIBudsOnDeviceVoiceAssistantAPI)]) {
    NSLog(@"On-device voice assistant is not supported");
    return;
}

NSLog(@"Current mode: %ld", (long)voiceAssistant.onDeviceVoiceAssistantMode);

if (voiceAssistant.onDeviceVoiceAssistantCapability !=
    AIBudsOnDeviceVoiceAssistantCapabilityCommon) {
    NSLog(@"Advanced mode is not supported");
    return;
}

[voiceAssistant
    setOnDeviceVoiceAssistantMode:AIBudsOnDeviceVoiceAssistantModeAdvanced
                       completion:^(BOOL success, NSError *error) {
                           if (!success) {
                               NSLog(@"%@", error.localizedDescription ?: @"Unable to change mode");
                               return;
                           }
                           NSLog(@"Mode changed to advanced");
                       }];

注意事项

• .unknown 表示状态不可用，不得作为目标模式发送。
• 成功回调用于确认请求。应根据设备属性或模式变化代理回调刷新 UI。
• .advanced 包含通话状态语音控制，仅应对 .common 能力提供。
