The pyttsx library is a cross-platform wrapper that supports the native text-to-speech libraries of Windows and Linux at least, using SAPI5 on Windows and eSpeak on Linux.

07/09/2010 · The W3C specifications used by VXML to provide speech synthesis.

Energy sets the volume for a given sound, or part of sound.
Pitch is the frequency for that sound.
Rpt is the repeat bit.
K1-K10 are the reflection parameters index values.
With the TMS5520C, we don't have to use a fixed frame rate: we can alsospecify the rate for each frame, using two more bits at the beginningofeach frame to set the frame rate (see the command).

Speech synthesis is fully supported without prefixes

Some languages, such as Finnish, Italian, and Spanish, have very regular pronunciation. Sometimes there is almost one-to-one correspondence with letter to sound. The other end is for example French with very irregular pronunciation. Many languages, such as French, German, Danish and Portuguese also contain lots of special stress markers and other non ASCII characters (Oliveira et al. 1992). In German, the sentential structure differs largely from other languages. For text analysis, the use of capitalized letters with nouns may cause some problems because capitalized words are usually analyzed differently than others.

This recipe shows how to generate computer speech from text using the pyttsx Python library. Text-to-speech, or speech synthesis, has many useful applications.

What's the ideal text-to-speech …

For certain languages synthetic speech is easier to produce than in others. Also, the amount of potential users and markets are very different with different countries and languages which also affects how much resources are available for developing speech synthesis. Most of languages have also some special features which can make the development process either much easier or considerably harder.

In formant synthesis (see 5.2), the set of rules controlling the formant frequencies and amplitudes and the characteristics of the excitation source is large. Also some lack of naturalness, especially with nasalized sounds, is considered a major problem with formant synthesis.

"Linear Predictive Coding (LPC) synthesizes human speech byrecoveringfrom the original speech enough data to construct a time-varyingdigitalfilter model of the vocal tract. This filter is excited with a digitalrepresentation of either glottal air impulses (voiced sound) or therushof air, which produces unvoiced sound. The output of this filter modelis passed through a 8-bit digital-to-analog (D/A) converter to producea synthetic speech waveform."

There are many methods to produce speech sounds after text and prosodic analysis. All these methods have some benefits and problems of their own.

Posts about speech synthesis written by dennisaa

Timing at sentence level or grouping of words into phrases correctly is difficult because prosodic phrasing is not always marked in text by punctuation, and phrasal accentuation is almost never marked (Santen et al. 1997). If there is no breath pauses in speech or if they are in wrong places, the speech may sound very unnatural or even the meaning of the sentence may be misunderstood. For example, the input string "John says Peter is a liar" can be spoken as two different ways giving two different meanings as "John says: Peter is a liar" or "John, says Peter, is a liar". In the first sentence Peter is a liar, and in the second one the liar is John.

Speech Synthesis Markup Language (SSML) Version 1.1

Finding correct intonation, stress, and duration from written text is probably the most challenging problem for years to come. These features together are called prosodic or suprasegmental features and may be considered as the melody, rhythm, and emphasis of the speech at the perceptual level. The intonation means how the pitch pattern or fundamental frequency changes during speech. The prosody of continuous speech depends on many separate aspects, such as the meaning of the sentence and the speaker characteristics and emotions. The prosodic dependencies are shown in Figure 4.1. Unfortunately, written text usually contains very little information of these features and some of them change dynamically during speech. However, with some specific control characters this information may be given to a speech synthesizer.

Self Voicing — Ren'Py Documentation

This command is used to tell a TMS5520C synthesizer whether itshoulduse a fixed frame rate, or use the first two bits of each frame as aframerate (it is ignored by the older TMS5520). The command byte has theform:x0x0xvrr where v is the frame mode and rr the fixed frame rate. If v=0,rr will be used as a frame rate until further notice. If v=1, rr isirrelevantand the frame rate must be passed with each frame. The four possibleframerates are:
00: 200 samples/sec
01: 150 samples/sec
10: 100 samples/sec
11: 50 samples/sec
