Not necessarily.
If you already have audio recordings of the speech you want, then you usually do not need speech synthesis. Speech synthesis (text-to-speech, or TTS) is mainly useful when you want a computer-generated voice from text.
Use audio recordings if:
- You already have the spoken content recorded
- You want the original speaker’s voice
- You need natural human delivery, emotion, or style
- You’re making a replay, archive, or media playback app
Use speech synthesis if:
- You only have text, not recordings
- You want to generate speech dynamically
- You need to support many voices/languages
- You want consistent output without recording each phrase
You might use both if:
- You want recordings as the primary source, but TTS as a fallback
- You want to generate missing phrases or alerts
- You’re building an accessibility tool that can read text when no recording is available
If you want, I can also help you decide based on your specific project or compare audio recording vs speech synthesis in a simple table.
