Core Features and Capabilities

Fish Audio delivers a suite of tools and features that streamline the process of audio content creation. This section provides a detailed look at the core capabilities that define the platform.
Text-to-Speech (TTS)
The text-to-speech functionality of Fish Audio transforms written text into natural, lifelike speech. Some of the key aspects include:
- Natural Sounding Voices: Fish Audio utilizes advanced machine learning models that generate voices with an exceptionally natural cadence and intonation, closely mimicking human speech.
- Customization Options: Users can tweak aspects such as speed, pitch, and volume. These controls allow for tailored outputs that fit the unique requirements of different projects—whether it’s a dramatic storytelling narrative or a professional business presentation.
- Multilingual Support: With support for over 40 languages, including English, French, Japanese, and Arabic, Fish Audio enables the creation of global content. This multilingual capacity is particularly valuable for organizations seeking to reach a diverse audience.

Voice Cloning
Voice cloning is one of Fish Audio’s flagship features that sets it well apart from conventional TTS services. The voice cloning process is designed to be both intuitive and technically sophisticated:
- Rapid Cloning Process: Using as little as 15–30 seconds of audio input, users can create a near-real digital replica of any voice. This feature is ideal for creating personalized voiceovers or replicating the vocal style of a celebrity or public figure.
- High Fidelity and Realism: The cloned voices capture nuanced speech characteristics such as tone, pace, and emotional inflection, ensuring that the output is nearly indistinguishable from the source voice.
- Flexible Input Options: Users can either upload pre-recorded audio files or use the platform’s built-in recording tool, making the process accessible regardless of available resources.
The voice cloning aspect is a major differentiator for Fish Audio. It allows content creators not only to generate new audio content but also to maintain brand consistency or create new digital personas for their work. More details are available on the voice cloning page.
Speech-to-Text (STT)
Fish Audio also integrates robust speech-to-text capabilities. This feature is designed to convert spoken language into written text with:
- High Accuracy: The advanced AI models used in the STT functionality result in precise transcriptions, making them useful for tasks like subtitle generation, meeting transcriptions, and voice command integrations.
- Seamless Workflow: The platform’s intuitive design ensures that switching between TTS, voice cloning, and STT is smooth, enabling users to create workflows that include both audio and text outputs.
Emotional Control and Tone Modification
Perhaps one of the most innovative features of Fish Audio is its ability to control the emotion and tone of the output speech, through the use of customizable markers:
- Expressiveness: With emotional markers like “angry,” “enthusiastic,” “sad,” or “warm,” users can imbue the generated voice with a range of feelings. This is particularly useful for applications in storytelling, digital marketing, and interactive media.
- Tone and Pausing: The interface allows for the specification of detailed directives such as pauses, breaks, and changes in intonation. For example, a script can begin with a “sincere” note or end with a “reflective pause,” creating a more dynamic and engaging audio presentation.
This emotional control sets Fish Audio apart from many competitors whose TTS engines offer a more static, monotone delivery.
Multi-Speaker Support
Fish Audio excels in scenarios where multiple distinct voices are required:
- Dynamic Dialogues: The platform supports the creation of conversations featuring different voice models. This is ideal for audio dramas, podcasts, and interactive narratives.
- Broad Voice Library: With access to over 200,000 voices, including both AI-generated and user-cloned options, the platform provides an impressive range of characterizations—from familiar celebrity voices to custom-created personas.
API Integration and Developer Support
For developers looking to integrate voice synthesis into their applications, Fish Audio offers a robust API:
- Flexible API: The API allows seamless integration, supporting tasks such as automated voice generation, dynamic real-time interactions, or complex workflows.
- Documentation: Comprehensive guides and examples are provided, enabling developers with varying levels of expertise to make the most of the platform.
For more technical insights, check out the API documentation on the Fish Audio Developer Portal.

Technical Deep Dive Into the S1 Model
At the heart of Fish Audio’s advanced capabilities is the S1 model—a state-of-the-art voice synthesis engine known for its emotional control, tone customization, and multi-speaker support. A deep dive into the S1 model reveals why it is considered best in class.
Emotional Nuance and Expressiveness
The S1 model is designed to capture a wide range of human emotions with remarkable precision. Some key technical highlights include:
- Fine-Grained Emotional Markers: Users can insert markers within the text to denote varying emotional states. For instance, a voice can be prompted to sound “enthusiastic” at the start of a sentence and transition to a “reflective” tone later on. This level of control is rarely seen in competing platforms.
- Parallel Paralinguistic Features: Beyond basic emotions, the S1 model supports subtle cues such as laughter, pauses, and sighs. These features contribute to a more realistic speech pattern that mirrors natural conversational dynamics.
- Real-Time Adjustments: Changing the temperature or top-p parameters in the generation process allows adjustments in randomness and coherence. Lower temperatures yield more consistent and predictable outputs, while higher values introduce creative variations—ideal for applications where unpredictability is valued.
Tone, Pacing, and Pronunciation Control
Precision in tone and pacing is another cornerstone of the S1 model’s output:
- Customizable Tuning: Users can fine-tune the output not just at the sentence level but down to the syllable. Adjustments in pitch, speed, and volume help match the voice output to the desired context—be it dramatic narration or a friendly advertisement.
- Phoneme-Level Control: The S1 model allows for precise pronunciation adjustments. This is particularly useful for languages or names that are prone to mispronunciation by generic TTS systems.
- Dynamic Pausing: The system supports inserting breaks or pauses within the text through bracketed commands, ensuring that the cadence feels natural. For example, a narrator can be made to pause after an impactful sentence, providing a dramatic effect.
Multi-Lingual and Multi-Speaker Advances
The S1 model is optimized for global use:
- Support for Multiple Languages: In addition to English, the model performs well in several major languages, allowing content creators to produce multilingual audio content without losing the speaker’s unique character.
- Inter-Speaker Variability: When dealing with multiple voice outputs in a single session, the S1 model maintains distinct intonations for each speaker. This makes it ideal for projects like audiobooks and dialogues where each character’s voice must be clearly distinguishable.
- Voice Cloning Fidelity: The voice cloning functionality within S1 is engineered to achieve high fidelity. Even with as little as 15–30 seconds of input, the system captures the subtleties of the target voice—including emotional depth, pitch variations, and idiosyncratic speech patterns.
For developers and technical enthusiasts, these features underscore the S1 model’s capacity to tackle complex synthesis tasks. More technical details can be found on the Fish Audio GitHub repository.
