1. Libraries and Tools Used: |
|
- Transformers: Provides the `VitsModel` and `AutoTokenizer`, with the use of `facebook/mms-tts-eng` model, a sophisticated text-to-speech model designed by Facebook. |
|
- Torch: A companion library for Transformers, essential for processing the data through the speech model. |
|
- Librosa: A library for audio processing, especially used here for pitch adjustment of the speech. |
|
- Soundfile: Utilized to save the speech output as an audio file. |
|
- Tempfile: Creates temporary files for intermediate storage during processing. |
|
- Gradio: Facilitates the creation of a user-friendly web interface for the text-to-speech application. |

2. Pipeline for Text-to-Speech Conversion: |
|
- Text Input: You begin by typing in the text you want to be converted into speech. |
|
- Tokenization: `AutoTokenizer` processes this text, preparing it for the speech model. |
|
- Speech Synthesis: The `facebook/mms-tts-eng` model within the `VitsModel` takes this processed text and generates the spoken words. |
|
- Pitch Adjustment: 0 Pitch Value: Represents the normal, unaltered pitch of the speech. This is the default state where the voice sounds as it naturally would, without any modifications. |
|
Negative Pitch Values: When you set the pitch to a negative value, it makes the voice sound higher. This is similar to moving up the notes on a piano, resulting in a higher, perhaps more youthful or feminine tone. |
|
Positive Pitch Values: Conversely, positive pitch values make the voice sound lower. This is akin to moving down the notes on a piano. A positive pitch shift results in a deeper, more resonant tone, often associated with a more masculine or mature voice. |
|
- Saving Audio: The speech with the adjusted pitch is saved as an audio file using `Soundfile` and `Tempfile`. |
|
- Interactive Web Interface: Gradio provides an interface where you input text, adjust the pitch using a slider, and listen to the speech output. |
