Why not use translation component ? But for your question you can use function or filter:

$di->set('view', function () use ($di) {
    $view = new \Phalcon\Mvc\View\Simple();
    $volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di);
    $compiler=$volt->getCompiler();
    $compiler->addFilter('attribute', function ($resolvedArgs, $exprArgs)
    {
        return vsprintf('%s->{%s}', explode(', ', $resolvedArgs));
    });
    $view->registerEngines([
        'volt' => $volt
    ]);
    return $view;
});

And then in view : {{ object|attribute(xyz) }}

$di->set('view', function () use ($di) {
    $view = new \Phalcon\Mvc\View\Simple();
    $volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di);
    $compiler=$volt->getCompiler();
    $compiler->addFunction('attribute', function ($resolvedArgs, $exprArgs)
    {
        return vsprintf('%s->{%s}', explode(', ', $resolvedArgs));
    });
    $view->registerEngines([
        'volt' => $volt
    ]);
    return $view;
});

And then in view : {{ attribute(object,xyz) }}

Twig for example don't support it too(you have use getAttribute).
