新版的没有唤醒词选择了。

把这个降回去就可以了.

I think the maximum wake words to select is 2 due to the CPU usage of the chip.

Thanks.
Btw, in aliepress there is Xiaozhi AI Chatbot with an SDCard Slot (TF Card), and check some of board config.h have TF Card gpio pin.
It's posible to make Xiaozhi AI Chatbot to play Audio file on the SD Card?

[78]

Yes. It's possible. It's easy to find an ESP32 sample project to play audio file on SD card. Claude and ChatGPT can also handle this.

Thanks for the reply,
What i want to know, if i can add TF Card and use it with xiaozhi-esp32 firmware, then i can ask the Chatbot, "Hi Lily, play the audio with the name music.ogg on the SD Card"
to play the file music.ogg that i put on the SD Card.

Of course. This is a piece of sample code you can implement in your custom board class:

    std::string GetSdcardAudioList() {
        return "[{\"name\": \"test.mp3\", \"size\": 1000}]";
    }

    std::string PlaySdcardAudio(const std::string& name) {
        if (true) {
            return "{\"status\": \"playing\"}";
        } else {
            return "{\"status\": \"audio file not found\"}";
        }
    }

    // IoT initialization, gradually migrating to MCP protocol
    void InitializeTools() {
        auto& mcp_server = McpServer::GetInstance();

        // SDCard audio list retrieval tool
        mcp_server.AddTool("self.sdcard.get_audio_list",
            "Get a list of all audio files in SDCard",
            PropertyList(),
            [this](const PropertyList& properties) -> ReturnValue {
                return GetSdcardAudioList();
            });

        // SDCard audio playback tool
        mcp_server.AddTool("self.sdcard.play_audio",
            "Play a specified audio file from SDCard",
            PropertyList({
                Property("name", kPropertyTypeString, "The name of the audio file to play")
            }),
            [this](const PropertyList& properties) -> ReturnValue {
                std::string name = properties["name"].value<std::string>();
                return PlaySdcardAudio(name);
            });
    }

                return GetSdcardAudioList();
            });

            "Play a specified audio file from SDCard",

                return PlaySdcardAudio(name);
            });
    }

Thanks.
Is there board that already have a feature to play audio file using that class?
or the xiaozhi-esp32 doesn't have that feature.

[78]

Ok. Fixed

[78]

Of course there are some boards have implemented this function. But we want to keep the project focused and extendable. These PRs are not merged into the main branch.

Thanks for the replay, can you give me the link to the board?
or github project that have that have implemented this function

Check this: #863

[TeguhTeknisi]

Check this: #863

oke, thanks.
for anyone else reading this, and want to know, go to this link
https://github.com/Maggotxy/xiaozhi-esp32-music
and this https://github.com/104gogo/xiaozhi-esp32/tree/feat/play-mp3
afaik, but its only capable play online music and need to register.... -_-
