Text to Speech¶
Speech Studio's core feature converts written text into natural-sounding audio using Azure Cognitive Services neural voices. The output is virtually indistinguishable from a human speaker.
How It Works¶
Speech Studio sends your text to Azure's neural text-to-speech engine, which processes it and returns high-quality audio. The entire operation happens in real time, and your text data is not stored on any external server.
Using Text to Speech¶
- Enter text -- Type or paste your content into the main text area. There is no strict character limit, but very long texts may take longer to process.
- Select a voice -- Choose from 603 AI voices across 80+ languages. Use the filter options to narrow down by language, gender, or voice style.
- Adjust parameters -- Modify speed, pitch, and volume using the sliders or input fields.
- Click Convert -- The audio is generated and ready for preview within seconds.
- Save the file -- Export in MP3, WAV, or OGG format.
Supported Input¶
- Plain text (typed or pasted)
- Text imported from
.txtfiles - SSML markup for advanced control (see SSML Support)
Audio Quality¶
Speech Studio uses Azure's latest neural voice models, which produce studio-quality audio with natural intonation, breathing pauses, and emphasis. The voices support:
- Conversational and formal speaking styles
- Emotional expression (happy, sad, excited, and more)
- Whispering, shouting, and narration styles (on supported voices)
Pro Tip
For the best results with longer content, break your text into paragraphs. This gives the AI voice engine clear context for each section, resulting in more natural delivery.
Privacy¶
Your text is processed through Azure Cognitive Services to generate audio, but it is not stored, logged, or used for training by Microsoft or Kaizen Apps. Once the audio is generated, the text is discarded from memory.
