Usage Methods

​
Read Aloud

The most common way to use TTS — have EnConvo read text aloud in real time.
  1. Select any text on your screen
  2. Trigger the Read Aloud command from the SmartBar or PopBar
  3. EnConvo streams the audio as it generates, so playback starts almost immediately
You can also click the speaker icon on any AI chat response to read it aloud.

​
Text to Audio File

Convert text into a saved audio file for later use.
  1. Open the TTS (Text To Speech) command
  2. Enter or paste the text you want to convert
  3. The audio file is saved to your specified output directory
  4. Use the Show in Finder or Save As actions to manage the file

​
Gemini TTS (Style-Controlled)

Gemini TTS offers unique style-controlled speech generation. Single Speaker: 
Read aloud with a dramatic flair: It was a dark and stormy night..
Multi-Speaker (dialog): 
Read aloud in a warm, welcoming tone
Speaker 1: Hello! We're excited to show you our native speech capabilities
Speaker 2: Where you can direct a voice, create realistic dialog, and so much more.
Gemini TTS supports models like Gemini 2.5 Flash Preview TTS and Gemini 2.5 Pro Preview TTS, with voice options such as Zephyr, Puck, and more.

​
Convert SRT Subtitles to Audio

Convert subtitle files to audio:
  1. Provide your .srt subtitle file
  2. EnConvo processes each subtitle segment with the configured TTS provider
  3. Outputs a synchronized audio file

​
Using TTS in Chat

EnConvo integrates TTS directly into the AI chat experience:
  1. Manual playback: Click the speaker icon on any AI response to hear it read aloud
  2. Auto-TTS: Enable automatic TTS in chat settings to have every response read aloud
  3. Playback controls: Pause, resume, or stop playback at any time

​
Using TTS with Translation

The Translate command can automatically play TTS audio of the translated result:
  1. Open the Translator command settings
  2. Enable Automatically Play TTS Audio under the Text-to-Speech group
  3. Select your preferred TTS provider
  4. Every translation result is now read aloud automatically

​
Sound Effects Generation

EnConvo can also generate sound effects from text descriptions:
  1. Use the Text To Sound Effect command
  2. Describe the sound you want in English (up to 200 characters)
  3. The more detailed the description, the better the result
A gentle rain falling on a tin roof with distant thunder

​
Troubleshooting

  1. Check that your Mac’s audio output is working (System Settings > Sound)
  2. Verify the TTS provider is configured with valid credentials
  3. Try switching to Edge TTS or System TTS to rule out API issues
  4. Check the console logs for error messages
  1. Switch to a higher-quality provider like ElevenLabs or OpenAI TTS HD
  2. If using OpenAI, switch from tts-1 to tts-1-hd
  3. Adjust the speed — very high speeds can reduce quality
  4. Try a different voice; some voices perform better than others
  1. Use a turbo/flash model variant when available (e.g., ElevenLabs flash v2.5, MiniMax turbo)
  2. Edge TTS and System TTS are typically the fastest options
  3. Check your internet connection for cloud providers
  4. Try reducing the text length for faster initial playback
  1. For xAI TTS, explicitly set the language instead of using Auto Detect
  2. Use a multilingual voice like Azure’s EmmaMultilingualNeural
  3. Ensure the text language matches the voice’s supported languages
