This metapackage will install packages which are useful for Speech Synthesis and related APIs or applications.

Description

For a better overview of the project's availability as a Debian package, each head row has a color code according to this scheme:

If you discover a project which looks like a good candidate for Debian Accessibility to you, or if you have prepared an unofficial Debian package, please do not hesitate to send a description of that project to the Debian Accessibility mailing list

EFlite is a speech server for Emacspeak and other screen readers that allows them to interface with Festival Lite, a free text-to-speech engine developed at the CMU Speech Center as an off-shoot of Festival.

Due to limitations inherited from its backend, EFlite does only provide support for the English language at the moment.

eSpeak é um software sintetizador de voz para Inglês, e alguns outros idiomas.

eSpeak produz fala em Inglês de boa qualidade. Ele usa um método de síntese diferente de outros motores "texto para fala" (text to speech - TTS) de código aberto, e soa bastante diferente. Ele talvez não seja tão natural ou "suave", mas para alguns a articulação é clara e fácil de se ouvir por longos períodos.

Ele pode ser executado em linha de comando para ditar texto de um arquivo ou da entrada padrão.

  • Inclui diferentes Vozes, cujas características podem ser alteradas.
  • Pode produzir saída de fala como um arquivo WAV.
  • Pode traduzir texto para códigos fonéticos, sendo então adaptado como uma interface para outros motores de síntese de voz.

  • Potencial para outras línguas. Mais de 40 línguas inclusas.

  • Tamanho compacto. O programa e seus dados totalizam 350 kbytes.
  • Escritos em C++.

Flite is a small fast run-time speech synthesis engine. It is the latest addition to the suite of free software synthesis tools including University of Edinburgh's Festival Speech Synthesis System and Carnegie Mellon University's FestVox project, tools, scripts and documentation for building synthetic voices. However, flite itself does not require either of these systems to run.

It currently only supports the English and Indic languages.

This package contains the executables and documentation.

Speech Dispatcher fornece uma camada independente de dispositivo para síntese de voz. Ele suporta, como mecanismo, diferentes sintetizadores de voz em software e hardware e fornece uma camada genérica para síntese de voz e reprodução de dados PCM através desses diferentes mecanismos para aplicativos.

Vários conceitos de alto nível como enfileiramento versus voz interrompida e configurações do usuário da aplicação específica são implementados de maneira independente do dispositivo, portanto, liberando o programador do aplicativo de ter que, mais uma vez, reinventar a roda.

Este pacote contém o próprio Speech Dispatcher.

Recite é um programa para executar síntese de voz. A qualidade do som produzido não é excessivamente boa, mas ela deve ser adequada para relatar verbalmente as mensagens de erro ocasionais.

Ao receber algum texto em Inglês, recite irá convertê-lo em uma série de fonemas, então converterá esses fonemas em uma sequência de parâmetros de aparelho vocal, e então sintetizará o som que um aparelho vocal faria para dizer a sentença. Recite pode realizar um subconjunto dessas operações, então ele pode ser usado para converter texto em fonemas, ou para produzir uma expressão vocal baseada em parâmetros de aparelho vocal computados por outro programa.

Speech Dispatcher provides a device independent layer for speech synthesis. It supports various software and hardware speech synthesizers as backends and provides a generic layer for synthesizing speech and playing back PCM data via those different backends to applications.

Various high level concepts like enqueueing vs. interrupting speech and application specific user configurations are implemented in a device independent way, therefore freeing the application programmer from having to yet again reinvent the wheel.

This package contains dependencies on packages necessary for running Speech Dispatcher with Festival.

This Text-To-Speech (TTS) engine speaks French; a preliminary English support is also offered. The engine uses context-sensitive rules to produce phonemes from the text. It relies on MBROLA to generate actual audio output from the phonemes. The TTS engine is implemented using the Python programming language.

The upstream authors have come up with this TTS to try and meet their own needs as blind users. It's designed to be plugged as output to some screen-review software, firstly with BRLTTY. They favor speed and intelligibility over perfect pronunciation. Cicero is aimed to have a quick response time, the ability to quickly shut-up and skip to another utterance, intelligibility where it counts (not perfect pronunciation), the ability to track speech progression, relative simplicity (hackability) and relative small code size.

Mbrola is Thierry Dutoit's phonemizer for multilingual speech synthesis. The various diphone databases are distributed on separate packages, but they must be used with and only with Mbrola because of license matters. Read the copyright for details.

Mbrola itself doesn't provide full TTS. It is a speech synthesizer based on the concatenation of diphones. It takes a list of phonemes as input, together with prosodic information (duration of phonemes and a piecewise linear description of pitch), and produces speech samples on 16 bits (linear), at the sampling frequency of the diphone database.

Use Mbrola along with Freephone, cicero or espeak to have a complete text-to-speech in English.
