Maui Speech To Text

What it does

When your agent uses it

• : speech to text
• Speech recognition
• Microphone input
• Hands-free text

Example prompts

• “speech to text”
• “voice input”
• “speech recognition”
• “/maui-speech-to-text”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Wrap ISpeechToText in a service — Don't use SpeechToText.Default directly in ViewModels. Wrap in ISpeechRecognitionService for testability…
2. 2Use partial results for UX — Subscribe to PartialResultReceived for live transcription feedback. Users expect to see words appear as they…
3. 3Continuous listening = loop with delay — Loop StartListeningAsync with small delays (Task.Delay(100)) for conversation mode.
4. 4Guard against double-start — Check state before starting
5. 5Natural language output — CommunityToolkit.Maui returns normalized, punctuated text — not raw phonemes. No post-processing needed for…
6. 6UI-agnostic service — The ISpeechRecognitionService pattern works identically with XAML/MVVM, C# Markup, and MauiReactor. See…

What it can do on your machine

Read from SKILL.md and the folder at commit 79bb4bf. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are csharp).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Maui Speech To Text loads about 1.2k tokens when it runs, and up to ~4.4k if it reads all its reference files. Until then it costs about 139 tokens; SKILL.md has 312 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~139

When it runs · the whole SKILL.md, loaded when a task matches

~1.2k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~4.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Add speech-to-text voice input to .NET MAUI apps using CommunityToolkit.Maui. Covers speech recognition, microphone permissions, and hands-free text entry. Works with any UI pattern (XAML/MVVM, C# Markup, MauiReactor). USE FOR: "speech to text", "voice input", "speech recognition", "microphone input", "voice command", "dictation", "SpeechToText", "hands-free text", "transcribe speech". DO NOT USE FOR: text-to-speech output (different feature), media playback (use maui-media-picker), or general permissions (use maui-permissions).

// ❌ Starting recognition without checking permissions
var result = await _speechService.StartListeningAsync();

// ✅ Always check permissions first
if (!await _speechService.RequestPermissionsAsync())
    return; // Gracefully handle denial
var result = await _speechService.StartListeningAsync(cancellationToken);

// ❌ No timeout — listens forever if no speech detected
await _speechToText.StartListenAsync(options, CancellationToken.None);

// ✅ Use a combined timeout + user cancellation token
using var timeoutCts = new CancellationTokenSource(TimeSpan.FromSeconds(60));
using var combinedCts = CancellationTokenSource.CreateLinkedTokenSource(
    userCancellationToken, timeoutCts.Token);
await _speechToText.StartListenAsync(options, combinedCts.Token);

// ❌ Subscribe without unsubscribe
_speechToText.RecognitionResultUpdated += OnRecognitionResultUpdated;

// ✅ Always unsubscribe in finally block
try
{
    _speechToText.RecognitionResultUpdated += OnRecognitionResultUpdated;
    // ... listen ...
}
finally
{
    _speechToText.RecognitionResultUpdated -= OnRecognitionResultUpdated;
}

// ❌ Leaked CTS
_currentCts = new CancellationTokenSource();

// ✅ Dispose in finally
try { /* ... */ }
finally
{
    _currentCts?.Dispose();
    _currentCts = null;
}
