Features

Speech-to-Text API

Real-time Transcription

The AssemblyAI Speech-to-Text API provides real-time transcription with a high degree of accuracy. The API converts audio data to text, creating transcriptions for use in various applications.

This feature can be used for transcription and closed captioning in media content, such as video or podcast, or to transcribe meetings and other spoken conversations. The real-time nature of the service ensures that transcriptions are generated quickly and can be used immediately, streamlining workflows and improving accessibility.

Custom Vocabulary

The Speech-to-Text API allows users to create custom vocabularies to improve accuracy for domain-specific terminology. By providing a list of complex names, industry-specific jargon, or other specialized terms, the API can more accurately transcribe audio containing these terms. This feature is especially useful for legal, medical, or technical transcription applications, where accuracy is crucial.

The custom vocabulary feature also improves the API's ability to convert audio data to text by learning from user-provided data, resulting in more accurate transcriptions over time.

Speaker Diarization

AssemblyAI's Speech-to-Text API features speaker diarization, which identifies and separates different speakers in audio data. The API can label different speakers by assigning unique identifiers to each one, making it easier to differentiate between them later on.

This feature is especially useful for capturing meeting notes or transcribing interviews. The Speaker Diarization feature helps to improve overall accuracy by breaking down audio data into smaller snippets and increasing recognition accuracy for each individual.

Text-to-Speech API

70 Natural Voices

The AssemblyAI Text-to-Speech API offers a wide variety of natural-sounding voices to choose from, with more than 70 different language and region variations. With this feature, users can create audio recordings for use in a wide range of applications, such as virtual assistants, audiobooks, or telephone systems. The natural sound of the voices allows for a more personal and engaging user experience, while the wide range of languages ensures global accessibility.

Custom Intonation

The Text-to-Speech API enables users to customize intonation on a per-phrase basis, allowing for more expressive and natural-sounding audio recordings. This feature simulates the natural patterns of speech, including pitch, volume, and speed variations, creating a more authentic experience. The API can also provide additional voice effects, such as whispering, to add variety and personality to the audio recordings.

Real-Time Prosody

The Text-to-Speech API's Real-Time Prosody feature adjusts intonation and speech patterns based on the text input, creating smoother and more accurate audio translations. The feature can adapt to the specific user by analyzing spoken language patterns, resulting in personalized audio recordings. This feature is especially useful for chatbots or virtual assistants, where personalized responses are essential for creating an engaging experience.
