From 19b69efd67d85dcc28e32056a47fd35047fba588 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sat, 7 Jun 2025 23:13:07 +0000 Subject: [PATCH] Fix: Use mic as fallback for STT if naudiodon fails This commit addresses an issue where Speech-to-Text (STT) functionality would be disabled if the `naudiodon` package failed to build during installation. The `src/process/tts_process.js` file (which handles STT) has been modified to: 1. Attempt to load `naudiodon` first. 2. If `naudiodon` fails to load, attempt to load the `mic` package as an alternative. 3. The audio recording logic has been adapted to work with both `naudiodon` and `mic` APIs. Additionally, `package.json` has been updated to move `mic` from `dependencies` to `optionalDependencies`, making its behavior consistent with `naudiodon`. This change provides a fallback mechanism for audio recording, increasing the robustness of the STT feature across different platforms and environments where `naudiodon` might have build issues. --- package.json | 4 +- src/process/tts_process.js | 227 +++++++++++++++++++++++++++++-------- 2 files changed, 179 insertions(+), 52 deletions(-) diff --git a/package.json b/package.json index 25b6235..a8ba1be 100644 --- a/package.json +++ b/package.json @@ -10,7 +10,6 @@ "express": "^4.18.2", "google-translate-api-x": "^10.7.1", "groq-sdk": "^0.5.0", - "mic": "^2.1.2", "minecraft-data": "^3.78.0", "mineflayer": "^4.26.0", "mineflayer-armor-manager": "^2.0.1", @@ -33,7 +32,8 @@ "yargs": "^17.7.2" }, "optionalDependencies": { - "naudiodon": "^2.3.6" + "naudiodon": "^2.3.6", + "mic": "^2.1.2" }, "scripts": { "postinstall": "patch-package", diff --git a/src/process/tts_process.js b/src/process/tts_process.js index 59d97e5..2ce3dd5 100644 --- a/src/process/tts_process.js +++ b/src/process/tts_process.js @@ -17,32 +17,55 @@ const __dirname = path.dirname(__filename); let portAudio; let AudioIO; let SampleFormat16Bit; +let mic; // For mic library +let activeAudioLibrary = null; // 'naudiodon' or 'mic' (async () => { try { const naudiodonModule = await import('naudiodon'); - portAudio = naudiodonModule.default; // CommonJS modules often export functionality on 'default' when imported into ES modules + portAudio = naudiodonModule.default; if (portAudio && typeof portAudio.AudioIO === 'function' && typeof portAudio.SampleFormat16Bit !== 'undefined') { AudioIO = portAudio.AudioIO; SampleFormat16Bit = portAudio.SampleFormat16Bit; + activeAudioLibrary = 'naudiodon'; console.log('[STT] naudiodon loaded successfully.'); } else if (naudiodonModule.AudioIO && typeof naudiodonModule.SampleFormat16Bit !== 'undefined') { - // Fallback if 'default' is not used and properties are directly on the module AudioIO = naudiodonModule.AudioIO; SampleFormat16Bit = naudiodonModule.SampleFormat16Bit; - portAudio = naudiodonModule; // Assign the module itself to portAudio for consistency if needed elsewhere + portAudio = naudiodonModule; + activeAudioLibrary = 'naudiodon'; console.log('[STT] naudiodon loaded successfully (direct properties).'); - } - else { + } else { throw new Error('AudioIO or SampleFormat16Bit not found in naudiodon module exports.'); } } catch (err) { - console.warn(`[STT] Failed to load naudiodon, Speech-to-Text will be disabled.
