+### Supported Features
+
+The supported features define the HFP capabilities of the device. The enumeration unfortunately differs between HF and AG sides.
+
+The AG supported features are set by combining the flags that start with HFP_AGSF_xx and calling hfp_ag_init_supported_features, followed by creating SDP record for the service using the same feature set.
+
+Similarly, the HF supported features are a combination of HFP_HFSF_xx flags and are configured by calling hfp_hf_init_supported_features, as well as creating an SDP record.

+### Audio Voice Recognition Activation
+
+Audio voice recognition (AVR) requires that HF and AG have following supported features enabled respectively: 
+- HF: HFP_HFSF_VOICE_RECOGNITION_FUNCTION and
+- AG: HFP_AGSF_VOICE_RECOGNITION_FUNCTION. 
+ 
+It can be activated or deactivated on both sides by calling:
+
+    // AG
+    uint8_t hfp_ag_activate_voice_recognition(hci_con_handle_t acl_handle);
+    uint8_t hfp_ag_deactivate_voice_recognition(hci_con_handle_t acl_handle);
+
+    // HF
+    uint8_t hfp_hf_activate_voice_recognition(hci_con_handle_t acl_handle);
+    uint8_t hfp_hf_deactivate_voice_recognition(hci_con_handle_t acl_handle);
+
+On either activation change, the HFP_SUBEVENT_VOICE_RECOGNITION_STATUS event will be emitted with status field set to ERROR_CODE_SUCCESS on success. The state field of this event indicates the current voice recognition state : 0 - if deactivated, 1 - if activated. 
+
+Voice recognition will stay active until either the deactivation command is called, or until the current Service Level Connection between the AG and the HF is dropped for any reason.
+
+| Use cases                                              |  Expected behavior  |
+|--------------------------------------------------------|---------------------|
+| No previous audio connection, AVR activated then deactivated | Audio connection will be opened by AG upon AVR activation, and upon AVR deactivation closed|
+| AVR activated and deactivated during existing audio connection | Audio remains active upon AVR deactivation |
+| Call to close audio connection during active VRA session       | The audio connection shut down will be refused |
+
+Beyond the audio routing and voice recognition activation capabilities, the rest of the voice recognition functionality is implementation dependent - the stack only provides the signaling for this.
