API

All bindings expose the same core methods:

Method	Returns	Description
to_ssml(input, platform)	string	Convert SpeechMarkdown to SSML for the given platform
to_text(input)	string	Convert SpeechMarkdown to plain text (strips all markup)
parse(input)	string (JSON)	Parse SpeechMarkdown and return the AST as JSON
is_speech_markdown(input)	bool	Check if a string contains SpeechMarkdown syntax
validate(input)	bool	Validate that SpeechMarkdown parses without errors

Usage

Rust

use speechmarkdown_rust::{SpeechMarkdownParser, Platform};

// Convert to SSML
let ssml = SpeechMarkdownParser::to_ssml(
    "Hello (world)[emphasis:\"strong\"]",
    Platform::AmazonAlexa,
)?;

// Convert to plain text
let text = SpeechMarkdownParser::to_text("Hello (world)[emphasis:\"strong\"]")?;

// Parse to AST (JSON string)
let ast = SpeechMarkdownParser::parse("Hello world")?;

// Check if input contains SpeechMarkdown syntax
if SpeechMarkdownParser::is_speech_markdown(&input) {
    // ...
}

// Validate input
SpeechMarkdownParser::validate(&input)?;

Python

from speechmarkdown_rust import to_ssml, to_text, parse, is_speech_markdown, validate

ssml = to_ssml('Hello (world)[emphasis:"strong"]', 'amazon-alexa')
text = to_text('Hello (world)[emphasis:"strong"]')
ast = parse('Hello world')

is_smd = is_speech_markdown('Hello (world)[emphasis:"strong"]')  # True
is_smd = is_speech_markdown('Hello world')                       # False

validate('Hello (world)[emphasis:"strong"]')  # raises ValueError if invalid

Node.js

const { to_ssml, to_text, parse, is_speech_markdown, validate } = require('speechmarkdown')

const ssml = to_ssml('Hello (world)[emphasis:"strong"]', 'amazon-alexa')
const text = to_text('Hello (world)[emphasis:"strong"]')
const ast = parse('Hello world')

is_speech_markdown('Hello (world)[emphasis:"strong"]')  // true
is_speech_markdown('Hello world')                       // false

validate('Hello (world)[emphasis:"strong"]')  // throws if invalid

.NET (C#)

using SpeechMarkdown;

var parser = new SpeechMarkdownParser();

string ssml = parser.ToSsml("Hello (world)[emphasis:\"strong\"]", Platform.AmazonAlexa);
string text = parser.ToText("Hello (world)[emphasis:\"strong\"]");
string json = parser.ParseToJson("Hello world");

bool isSmd = parser.IsSpeechMarkdown("Hello (world)[emphasis:\"strong\"]"); // true
parser.Validate("Hello (world)[emphasis:\"strong\"]"); // throws on invalid

Swift

import SpeechMarkdown

let parser = SpeechMarkdownParser()

let ssml = try parser.toSsml(input: "Hello (world)[emphasis:\"strong\"]", platform: "amazon-alexa")
let text = try parser.toText(input: "Hello (world)[emphasis:\"strong\"]")
let json = try parser.parseToJson(input: "Hello world")

let isSmd = parser.isSpeechMarkdown(input: "Hello (world)[emphasis:\"strong\"]") // true
try parser.validate(input: "Hello (world)[emphasis:\"strong\"]") // throws on invalid

C API

#include "speechmarkdown.h"

// Convert to SSML
const char* ssml = speechmarkdown_to_ssml("Hello (world)[emphasis:\"strong\"]", "amazon-alexa");
speechmarkdown_free((char*)ssml);

// Convert to plain text
const char* text = speechmarkdown_to_text("Hello (world)[emphasis:\"strong\"]");
speechmarkdown_free((char*)text);

// Parse to JSON
const char* json = speechmarkdown_parse("Hello world");
speechmarkdown_free((char*)json);

// Check for SpeechMarkdown syntax
bool is_smd = speechmarkdown_is_speech_markdown("Hello (world)[emphasis:\"strong\"]");

// Validate
bool valid = speechmarkdown_validate("Hello (world)[emphasis:\"strong\"]");

// Get last error (thread-local)
const char* err = speechmarkdown_get_error();
